GNU LIBRARY GENERAL PUBLIC LICENSE
Version 2, June 1991
Copyright (C) 1991 Free Software Foundation, Inc.
675 Mass Ave, Cambridge, MA 02139, USA
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
[This is the first released version of the library GPL. It is
numbered 2 because it goes with version 2 of the ordinary GPL.]
Preamble
The licenses for most software are designed to take away your
freedom to share and change it. By contrast, the GNU General Public
Licenses are intended to guarantee your freedom to share and change
free software--to make sure the software is free for all its users.
This license, the Library General Public License, applies to some
specially designated Free Software Foundation software, and to any
other libraries whose authors decide to use it. You can use it for
your libraries, too.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
this service if you wish), that you receive source code or can get it
if you want it, that you can change the software or use pieces of it
in new free programs; and that you know you can do these things.
To protect your rights, we need to make restrictions that forbid
anyone to deny you these rights or to ask you to surrender the rights.
These restrictions translate to certain responsibilities for you if
you distribute copies of the library, or if you modify it.
For example, if you distribute copies of the library, whether gratis
or for a fee, you must give the recipients all the rights that we gave
you. You must make sure that they, too, receive or can get the source
code. If you link a program with the library, you must provide
complete object files to the recipients so that they can relink them
with the library, after making changes to the library and recompiling
it. And you must show them these terms so they know their rights.
Our method of protecting your rights has two steps: (1) copyright
the library, and (2) offer you this license which gives you legal
permission to copy, distribute and/or modify the library.
Also, for each distributor's protection, we want to make certain
that everyone understands that there is no warranty for this free
library. If the library is modified by someone else and passed on, we
want its recipients to know that what they have is not the original
version, so that any problems introduced by others will not reflect on
the original authors' reputations.
Finally, any free program is threatened constantly by software
patents. We wish to avoid the danger that companies distributing free
software will individually obtain patent licenses, thus in effect
transforming the program into proprietary software. To prevent this,
we have made it clear that any patent must be licensed for everyone's
free use or not licensed at all.
Most GNU software, including some libraries, is covered by the ordinary
GNU General Public License, which was designed for utility programs. This
license, the GNU Library General Public License, applies to certain
designated libraries. This license is quite different from the ordinary
one; be sure to read it in full, and don't assume that anything in it is
the same as in the ordinary license.
The reason we have a separate public license for some libraries is that
they blur the distinction we usually make between modifying or adding to a
program and simply using it. Linking a program with a library, without
changing the library, is in some sense simply using the library, and is
analogous to running a utility program or application program. However, in
a textual and legal sense, the linked executable is a combined work, a
derivative of the original library, and the ordinary General Public License
treats it as such.
Because of this blurred distinction, using the ordinary General
Public License for libraries did not effectively promote software
sharing, because most developers did not use the libraries. We
concluded that weaker conditions might promote sharing better.
However, unrestricted linking of non-free programs would deprive the
users of those programs of all benefit from the free status of the
libraries themselves. This Library General Public License is intended to
permit developers of non-free programs to use free libraries, while
preserving your freedom as a user of such programs to change the free
libraries that are incorporated in them. (We have not seen how to achieve
this as regards changes in header files, but we have achieved it as regards
changes in the actual functions of the Library.) The hope is that this
will lead to faster development of free libraries.
The precise terms and conditions for copying, distribution and
modification follow. Pay close attention to the difference between a
"work based on the library" and a "work that uses the library". The
former contains code derived from the library, while the latter only
works together with the library.
Note that it is possible for a library to be covered by the ordinary
General Public License rather than by this special one.
GNU LIBRARY GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License Agreement applies to any software library which
contains a notice placed by the copyright holder or other authorized
party saying it may be distributed under the terms of this Library
General Public License (also called "this License"). Each licensee is
addressed as "you".
A "library" means a collection of software functions and/or data
prepared so as to be conveniently linked with application programs
(which use some of those functions and data) to form executables.
The "Library", below, refers to any such software library or work
which has been distributed under these terms. A "work based on the
Library" means either the Library or any derivative work under
copyright law: that is to say, a work containing the Library or a
portion of it, either verbatim or with modifications and/or translated
straightforwardly into another language. (Hereinafter, translation is
included without limitation in the term "modification".)
"Source code" for a work means the preferred form of the work for
making modifications to it. For a library, complete source code means
all the source code for all modules it contains, plus any associated
interface definition files, plus the scripts used to control compilation
and installation of the library.
Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of
running a program using the Library is not restricted, and output from
such a program is covered only if its contents constitute a work based
on the Library (independent of the use of the Library in a tool for
writing it). Whether that is true depends on what the Library does
and what the program that uses the Library does.
1. You may copy and distribute verbatim copies of the Library's
complete source code as you receive it, in any medium, provided that
you conspicuously and appropriately publish on each copy an
appropriate copyright notice and disclaimer of warranty; keep intact
all the notices that refer to this License and to the absence of any
warranty; and distribute a copy of this License along with the
Library.
You may charge a fee for the physical act of transferring a copy,
and you may at your option offer warranty protection in exchange for a
fee.
2. You may modify your copy or copies of the Library or any portion
of it, thus forming a work based on the Library, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:
a) The modified work must itself be a software library.
b) You must cause the files modified to carry prominent notices
stating that you changed the files and the date of any change.
c) You must cause the whole of the work to be licensed at no
charge to all third parties under the terms of this License.
d) If a facility in the modified Library refers to a function or a
table of data to be supplied by an application program that uses
the facility, other than as an argument passed when the facility
is invoked, then you must make a good faith effort to ensure that,
in the event an application does not supply such function or
table, the facility still operates, and performs whatever part of
its purpose remains meaningful.
(For example, a function in a library to compute square roots has
a purpose that is entirely well-defined independent of the
application. Therefore, Subsection 2d requires that any
application-supplied function or table used by this function must
be optional: if the application does not supply it, the square
root function must still compute square roots.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Library,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Library, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote
it.
Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Library.
In addition, mere aggregation of another work not based on the Library
with the Library (or with a work based on the Library) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.
3. You may opt to apply the terms of the ordinary GNU General Public
License instead of this License to a given copy of the Library. To do
this, you must alter all the notices that refer to this License, so
that they refer to the ordinary GNU General Public License, version 2,
instead of to this License. (If a newer version than version 2 of the
ordinary GNU General Public License has appeared, then you can specify
that version instead if you wish.) Do not make any other change in
these notices.
Once this change is made in a given copy, it is irreversible for
that copy, so the ordinary GNU General Public License applies to all
subsequent copies and derivative works made from that copy.
This option is useful when you wish to copy part of the code of
the Library into a program that is not a library.
4. You may copy and distribute the Library (or a portion or
derivative of it, under Section 2) in object code or executable form
under the terms of Sections 1 and 2 above provided that you accompany
it with the complete corresponding machine-readable source code, which
must be distributed under the terms of Sections 1 and 2 above on a
medium customarily used for software interchange.
If distribution of object code is made by offering access to copy
from a designated place, then offering equivalent access to copy the
source code from the same place satisfies the requirement to
distribute the source code, even though third parties are not
compelled to copy the source along with the object code.
5. A program that contains no derivative of any portion of the
Library, but is designed to work with the Library by being compiled or
linked with it, is called a "work that uses the Library". Such a
work, in isolation, is not a derivative work of the Library, and
therefore falls outside the scope of this License.
However, linking a "work that uses the Library" with the Library
creates an executable that is a derivative of the Library (because it
contains portions of the Library), rather than a "work that uses the
library". The executable is therefore covered by this License.
Section 6 states terms for distribution of such executables.
When a "work that uses the Library" uses material from a header file
that is part of the Library, the object code for the work may be a
derivative work of the Library even though the source code is not.
Whether this is true is especially significant if the work can be
linked without the Library, or if the work is itself a library. The
threshold for this to be true is not precisely defined by law.
If such an object file uses only numerical parameters, data
structure layouts and accessors, and small macros and small inline
functions (ten lines or less in length), then the use of the object
file is unrestricted, regardless of whether it is legally a derivative
work. (Executables containing this object code plus portions of the
Library will still fall under Section 6.)
Otherwise, if the work is a derivative of the Library, you may
distribute the object code for the work under the terms of Section 6.
Any executables containing that work also fall under Section 6,
whether or not they are linked directly with the Library itself.
6. As an exception to the Sections above, you may also compile or
link a "work that uses the Library" with the Library to produce a
work containing portions of the Library, and distribute that work
under terms of your choice, provided that the terms permit
modification of the work for the customer's own use and reverse
engineering for debugging such modifications.
You must give prominent notice with each copy of the work that the
Library is used in it and that the Library and its use are covered by
this License. You must supply a copy of this License. If the work
during execution displays copyright notices, you must include the
copyright notice for the Library among them, as well as a reference
directing the user to the copy of this License. Also, you must do one
of these things:
a) Accompany the work with the complete corresponding
machine-readable source code for the Library including whatever
changes were used in the work (which must be distributed under
Sections 1 and 2 above); and, if the work is an executable linked
with the Library, with the complete machine-readable "work that
uses the Library", as object code and/or source code, so that the
user can modify the Library and then relink to produce a modified
executable containing the modified Library. (It is understood
that the user who changes the contents of definitions files in the
Library will not necessarily be able to recompile the application
to use the modified definitions.)
b) Accompany the work with a written offer, valid for at
least three years, to give the same user the materials
specified in Subsection 6a, above, for a charge no more
than the cost of performing this distribution.
c) If distribution of the work is made by offering access to copy
from a designated place, offer equivalent access to copy the above
specified materials from the same place.
d) Verify that the user has already received a copy of these
materials or that you have already sent this user a copy.
For an executable, the required form of the "work that uses the
Library" must include any data and utility programs needed for
reproducing the executable from it. However, as a special exception,
the source code distributed need not include anything that is normally
distributed (in either source or binary form) with the major
components (compiler, kernel, and so on) of the operating system on
which the executable runs, unless that component itself accompanies
the executable.
It may happen that this requirement contradicts the license
restrictions of other proprietary libraries that do not normally
accompany the operating system. Such a contradiction means you cannot
use both them and the Library together in an executable that you
distribute.
7. You may place library facilities that are a work based on the
Library side-by-side in a single library together with other library
facilities not covered by this License, and distribute such a combined
library, provided that the separate distribution of the work based on
the Library and of the other library facilities is otherwise
permitted, and provided that you do these two things:
a) Accompany the combined library with a copy of the same work
based on the Library, uncombined with any other library
facilities. This must be distributed under the terms of the
Sections above.
b) Give prominent notice with the combined library of the fact
that part of it is a work based on the Library, and explaining
where to find the accompanying uncombined form of the same work.
8. You may not copy, modify, sublicense, link with, or distribute
the Library except as expressly provided under this License. Any
attempt otherwise to copy, modify, sublicense, link with, or
distribute the Library is void, and will automatically terminate your
rights under this License. However, parties who have received copies,
or rights, from you under this License will not have their licenses
terminated so long as such parties remain in full compliance.
9. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify or
distribute the Library or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Library (or any work based on the
Library), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Library or works based on it.
10. Each time you redistribute the Library (or any work based on the
Library), the recipient automatically receives a license from the
original licensor to copy, distribute, link with or modify the Library
subject to these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties to
this License.
11. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Library at all. For example, if a patent
license would not permit royalty-free redistribution of the Library by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Library.
If any portion of this section is held invalid or unenforceable under any
particular circumstance, the balance of the section is intended to apply,
and the section as a whole is intended to apply in other circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
12. If the distribution and/or use of the Library is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Library under this License may add
an explicit geographical distribution limitation excluding those countries,
so that distribution is permitted only in or among countries not thus
excluded. In such case, this License incorporates the limitation as if
written in the body of this License.
13. The Free Software Foundation may publish revised and/or new
versions of the Library General Public License from time to time.
Such new versions will be similar in spirit to the present version,
but may differ in detail to address new problems or concerns.
Each version is given a distinguishing version number. If the Library
specifies a version number of this License which applies to it and
"any later version", you have the option of following the terms and
conditions either of that version or of any later version published by
the Free Software Foundation. If the Library does not specify a
license version number, you may choose any version ever published by
the Free Software Foundation.
14. If you wish to incorporate parts of the Library into other free
programs whose distribution conditions are incompatible with these,
write to the author to ask for permission. For software which is
copyrighted by the Free Software Foundation, write to the Free
Software Foundation; we sometimes make exceptions for this. Our
decision will be guided by the two goals of preserving the free status
of all derivatives of our free software and of promoting the sharing
and reuse of software generally.
NO WARRANTY
15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
DAMAGES.
END OF TERMS AND CONDITIONS
Appendix: How to Apply These Terms to Your New Libraries
If you develop a new library, and you want it to be of the greatest
possible use to the public, we recommend making it free software that
everyone can redistribute and change. You can do so by permitting
redistribution under these terms (or, alternatively, under the terms of the
ordinary General Public License).
To apply these terms, attach the following notices to the library. It is
safest to attach them to the start of each source file to most effectively
convey the exclusion of warranty; and each file should have at least the
"copyright" line and a pointer to where the full notice is found.
<one line to give the library's name and a brief idea of what it does.>
Copyright (C) <year> <name of author>
This library is free software; you can redistribute it and/or
modify it under the terms of the GNU Library General Public
License as published by the Free Software Foundation; either
version 2 of the License, or (at your option) any later version.
This library is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU
Library General Public License for more details.
You should have received a copy of the GNU Library General Public
License along with this library; if not, write to the Free
Software Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
Also add information on how to contact you by electronic and paper mail.
You should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the library, if
necessary. Here is a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in the
library `Frob' (a library for tweaking knobs) written by James Random Hacker.

/* alloca.c -- allocate automatically reclaimed memory
(Mostly) portable public-domain implementation -- D A Gwyn
This implementation of the PWB library alloca function,
which is used to allocate space off the run-time stack so
that it is automatically reclaimed upon procedure exit,
was inspired by discussions with J. Q. Johnson of Cornell.
J.Otto Tennant <jot@cray.com> contributed the Cray support.
There are some preprocessor constants that can
be defined when compiling for your specific system, for
improved efficiency; however, the defaults should be okay.
The general concept of this implementation is to keep
track of all alloca-allocated blocks, and reclaim any
that are found to be deeper in the stack than the current
invocation. This heuristic does not reclaim storage as
soon as it becomes invalid, but it will do so eventually.
As a special case, alloca(0) reclaims storage without
allocating any. It is a good idea to use alloca(0) in
your main control loop, etc. to force garbage collection. */

.SH DESCRIPTION
This manual page
documents the GNU version of
.BR cpio .
.B cpio
copies files into or out of a cpio or tar archive, which is a file that
contains other files plus information about them, such as their
file name, owner, timestamps, and access permissions. The archive can
be another file on the disk, a magnetic tape, or a pipe.
.B cpio
has three operating modes.
.PP
In copy-out mode,
.B cpio
copies files into an archive. It reads a list of filenames, one per
line, on the standard input, and writes the archive onto the standard
output. A typical way to generate the list of filenames is with the
.B find
command; you should give
.B find
the \-d option to minimize problems with permissions on
directories that are unwritable or not searchable.
.PP
In copy-in mode,
.B cpio
copies files out of an archive or lists the archive contents. It
reads the archive from the standard input. Any non-option command
line arguments are shell globbing patterns; only files in the archive
whose names match one or more of those patterns are copied from the
archive. Unlike in the shell, an initial `.' in a filename does
match a wildcard at the start of a pattern, and a `/' in a filename
can match wildcards. If no patterns are given, all files are
extracted.
.PP
In copy-pass mode,
.B cpio
copies files from one directory tree to another, combining the
copy-out and copy-in steps without actually using an archive.
It reads the list of files to copy from the standard input; the
directory into which it will copy them is given as a non-option
argument.
.PP
.B cpio
supports the following archive formats: binary, old ASCII, new
ASCII, crc, HPUX binary, HPUX old ASCII, old tar, and POSIX.1 tar.
The binary format
is obsolete because it encodes information about the files in a way
that is not portable between different machine architectures.
The old ASCII format is portable between different machine architectures,
but should not be used on file systems with more than 65536 i-nodes.
The new ASCII format is portable between different machine architectures
and can be used on any size file system, but is not supported by all
versions of
.BR cpio ;
currently, it is only supported by GNU and Unix System V R4.
The crc format is
like the new ASCII format, but also contains a checksum for each file
which
.B cpio
calculates when creating an archive
and verifies when the file is extracted from the archive.
The HPUX formats are provided for compatibility with HPUX's cpio which
stores device files differently.
.PP
The tar format is provided for compatibility with
the
.B tar
program. It can not be used to archive files with names
longer than 100 characters, and can not be used to archive "special"
(block or character devices) files.
The POSIX.1 tar format can not be used to archive files with names longer
than 255 characters (less unless they have a "/" in just the right place).
.PP
By default,
.B cpio
creates binary format archives, for compatibility with
older
.B cpio
programs.
When extracting from archives,
.B cpio
automatically recognizes which kind of archive it is reading and can
read archives created on machines with a different byte-order.
.PP
Some of the options to
.B cpio
apply only to certain operating modes; see the SYNOPSIS section for a
list of which options are allowed in which modes.
.SS OPTIONS
.TP
.I "\-0, \-\-null"
In copy-out and copy-pass modes, read a list of filenames terminated
by a null character instead of a newline, so that files whose names
contain newlines can be archived. GNU
.B find
is one way to produce a list of null-terminated filenames.
.TP
.I "\-a, \-\-reset-access-time"
Reset the access times of files after reading them, so that it does
not look like they have just been read.
.TP
.I "\-A, \-\-append"
Append to an existing archive. Only works in copy-out mode. The
archive must be a disk file specified with the
.I \-O
or
.I "\-F (\-\-file)"
option.
.TP
.I "\-b, \-\-swap"
In copy-in mode, swap both halfwords of words and bytes of halfwords
in the data. Equivalent to
.IR "\-sS" .
Use this option to convert 32-bit integers between big-endian and
little-endian machines.
.TP
.I "\-B"
Set the I/O block size to 5120 bytes. Initially the block size is 512
bytes.
.TP
.I "\-\-block-size=BLOCK-SIZE"
Set the I/O block size to BLOCK-SIZE * 512 bytes.
.TP
.I "\-c"
Use the old portable (ASCII) archive format.
.TP
.I "\-C IO-SIZE, \-\-io-size=IO-SIZE"
Set the I/O block size to IO-SIZE bytes.
.TP
.I "\-d, \-\-make-directories"
Create leading directories where needed.
.TP
.I "\-E FILE, \-\-pattern-file=FILE"
In copy-in mode, read additional patterns specifying filenames to
extract or list from FILE. The lines of FILE are treated as if they
had been non-option arguments to
.BR cpio .
.TP
.I "\-f, \-\-nonmatching"
Only copy files that do not match any of the given patterns.
.TP
.I "\-F, \-\-file=archive"
Archive filename to use instead of standard input or output. To use a
tape drive on another machine as the archive, use a filename that
starts with `HOSTNAME:'. The hostname can be preceded by a
username and an `@' to access the remote tape drive as that user, if
you have permission to do so (typically an entry in that user's
`~/.rhosts' file).
.TP
.I "\-\-force-local"
With
.IR \-F ,
.IR \-I ,
or
.IR \-O ,
take the archive file name to be a local file even if it contains a
colon, which would ordinarily indicate a remote host name.
.TP
.I "\-H FORMAT, \-\-format=FORMAT"
Use archive format FORMAT. The valid formats are listed below;
the same names are also recognized in all-caps. The default in
copy-in mode is to automatically detect the archive format, and in
copy-out mode is "bin".
.RS
.IP bin
The obsolete binary format.
.IP odc
The old (POSIX.1) portable format.
.IP newc
The new (SVR4) portable format, which supports file systems having
more than 65536 i-nodes.
.IP crc
The new (SVR4) portable format with a checksum added.
.IP tar
The old tar format.
.IP ustar
The POSIX.1 tar format. Also recognizes GNU
.B tar
archives, which are similar but not identical.
.IP hpbin
The obsolete binary format used by HPUX's cpio (which stores device files
differently).
.IP hpodc
The portable format used by HPUX's cpio (which stores device files differently).
.RE
.TP
.I "\-i, \-\-extract"
Run in copy-in mode.
.TP
.I "\-I archive"
Archive filename to use instead of standard input. To use a
tape drive on another machine as the archive, use a filename that
starts with `HOSTNAME:'. The hostname can be preceded by a
username and an `@' to access the remote tape drive as that user, if
you have permission to do so (typically an entry in that user's
`~/.rhosts' file).
.TP
.I \-k
Ignored; for compatibility with other versions of
.BR cpio .
.TP
.I "\-l, \-\-link"
Link files instead of copying them, when possible (usable only with the
.I \-p
option).
.TP
.I "\-L, \-\-dereference"
Dereference symbolic links (copy the files that they point to instead
of copying the links).
.TP
.I "\-m, \-\-preserve-modification-time"
Retain previous file modification times when creating files.
.TP
.I "\-M MESSAGE, \-\-message=MESSAGE"
Print MESSAGE when the end of a volume of the backup media (such as a
tape or a floppy disk) is reached, to prompt the user to insert a new
volume. If MESSAGE contains the string "%d", it is replaced by the
current volume number (starting at 1).
.TP
.I "\-n, \-\-numeric-uid-gid"
In the verbose table of contents listing, show numeric UID and GID
instead of translating them into names.
.TP
.I " \-\-no-absolute-filenames"
In copy-in mode, create all files relative to the current directory,
even if they have an absolute file name in the archive.
.TP
.I " \-\-no-preserve-owner"
In copy-in mode and copy-pass mode, do not change the ownership of the
files; leave them owned by the user extracting them. This is the
default for non-root users, so that users on System V don't
inadvertently give away files.
.TP
.I "\-o, \-\-create"
Run in copy-out mode.
.TP
.I "\-O archive"
Archive filename to use instead of standard output. To use a tape
drive on another machine as the archive, use a filename that starts
with `HOSTNAME:'. The hostname can be preceded by a username and an
`@' to access the remote tape drive as that user, if you have
permission to do so (typically an entry in that user's `~/.rhosts'
file).
.TP
.I " \-\-only-verify-crc"
When reading a CRC format archive in copy-in mode, only verify the
CRC's of each file in the archive, don't actually extract the files.
.TP
.I "\-p, \-\-pass-through"
Run in copy-pass mode.
.TP
.I "\-\-quiet"
Do not print the number of blocks copied.
.TP
.I "\-r, \-\-rename"
Interactively rename files.
.TP
.I "\-R [user][:.][group], \-\-owner [user][:.][group]"
In copy-out and copy-pass modes, set the ownership of all files created
to the specified user and/or group. Either the user or the group, or
both, must be present. If the group is omitted but the ":" or "."
separator is given, use the given user's login group. Only the
super-user can change files' ownership.
.TP
.I "\-\-sparse"
In copy-out and copy-pass modes, write files with large blocks of zeros
as sparse files.
.TP
.I "\-s, \-\-swap-bytes"
In copy-in mode, swap the bytes of each halfword (pair of bytes) in the
files.
.TP
.I "\-S, \-\-swap-halfwords"
In copy-in mode, swap the halfwords of each word (4 bytes) in the
files.
.TP
.I "\-t, \-\-list"
Print a table of contents of the input.
.TP
.I "\-u, \-\-unconditional"
Replace all files, without asking whether to replace existing newer
files with older files.
.TP
.I "\-v, \-\-verbose"
List the files processed, or with
.IR \-t ,
give an `ls \-l' style table of contents listing. In a verbose table
of contents of a ustar archive, user and group names in the archive
that do not exist on the local system are replaced by the names that
correspond locally to the numeric UID and GID stored in the archive.
.TP
.I "\-V \-\-dot"
Print a "." for each file processed.
.TP
.I "\-\-version"
Print the
.B cpio
program version number and exit.

GNU cpio copies files into or out of a cpio or tar archive, The archive
can be another file on the disk, a magnetic tape, or a pipe.
GNU cpio supports the following archive formats: binary, old ASCII, new
ASCII, crc, HPUX binary, HPUX old ASCII, old tar, and POSIX.1 tar. The
tar format is provided for compatability with the tar program. By
default, cpio creates binary format archives, for compatibility with
older cpio programs. When extracting from archives, cpio automatically
recognizes which kind of archive it is reading and can read archives
created on machines with a different byte-order.

@chapter Tutorial
@cindex creating a cpio archive
@cindex extracting a cpio archive
@cindex copying directory structures
@cindex passing directory structures
GNU cpio performs three primary functions. Copying files to an
archive, Extracting files from an archive, and passing files to another
directory tree. An archive can be a file on disk, one or more floppy
disks, or one or more tapes.
When creating an archive, cpio takes the list of files to be processed
from the standard input, and then sends the archive to the standard
output, or to the device defined by the @samp{-F} option.
@xref{Copy-out mode}. Usually find or ls is used to provide this list
to the standard input. In the following example you can see the
possibilities for archiving the contents of a single directory.
@example
@cartouche
% ls | cpio -ov > directory.cpio
@end cartouche
@end example
The @samp{-o} option creates the archive, and the @samp{-v} option
prints the names of the files archived as they are added. Notice that
the options can be put together after a single @samp{-} or can be placed
separately on the command line. The @samp{>} redirects the cpio output
to the file @samp{directory.cpio}.
If you wanted to archive an entire directory tree, the find command can
provide the file list to cpio:
@example
@cartouche
% find . -print -depth | cpio -ov > tree.cpio
@end cartouche
@end example
This will take all the files in the current directory, the directories
below and place them in the archive tree.cpio. Again the @samp{-o}
creates an archive, and the @samp{-v} option shows you the name of the
files as they are archived. @xref{Copy-out mode}. Using the `.' in the
find statement will give you more flexibility when doing restores, as it
will save file names with a relative path vice a hard wired, absolute
path. The @samp{-depth} option forces @samp{find} to print of the
entries in a directory before printing the directory itself. This
limits the effects of restrictive directory permissions by printing the
directory entries in a directory before the directory name itself.
Extracting an archive requires a bit more thought because cpio will not
create directories by default. Another characteristic, is it will not
overwrite existing files unless you tell it to.
@example
@cartouche
% cpio -iv < directory.cpio
@end cartouche
@end example
This will retrieve the files archived in the file directory.cpio and
place them in the present directory. The @samp{-i} option extracts the
archive and the @samp{-v} shows the file names as they are extracted.
If you are dealing with an archived directory tree, you need to use the
@samp{-d} option to create directories as necessary, something like:
@example
@cartouche
% cpio -idv < tree.cpio
@end cartouche
@end example
This will take the contents of the archive tree.cpio and extract it to
the current directory. If you try to extract the files on top of files
of the same name that already exist (and have the same or later
modification time) cpio will not extract the file unless told to do so
by the -u option. @xref{Copy-in mode}.
In copy-pass mode, cpio copies files from one directory tree to another,
combining the copy-out and copy-in steps without actually using an
archive. It reads the list of files to copy from the standard input;
the directory into which it will copy them is given as a non-option
argument. @xref{Copy-pass mode}.
@example
@cartouche
% find . -depth -print0 | cpio --null -pvd new-dir
@end cartouche
@end example
The example shows copying the files of the present directory, and
sub-directories to a new directory called new-dir. Some new options are
the @samp{-print0} available with GNU find, combined with the
@samp{--null} option of cpio. These two options act together to send
file names between find and cpio, even if special characters are
embedded in the file names. Another is @samp{-p}, which tells cpio to
pass the files it finds to the directory @samp{new-dir}.

@section Copy-out mode
In copy-out mode, cpio copies files into an archive. It reads a list
of filenames, one per line, on the standard input, and writes the
archive onto the standard output. A typical way to generate the list
of filenames is with the find command; you should give find the -depth
option to minimize problems with permissions on directories that are
unreadable.

@section Copy-in mode
In copy-in mode, cpio copies files out of an archive or lists the
archive contents. It reads the archive from the standard input. Any
non-option command line arguments are shell globbing patterns; only
files in the archive whose names match one or more of those patterns are
copied from the archive. Unlike in the shell, an initial `.' in a
filename does match a wildcard at the start of a pattern, and a `/' in a
filename can match wildcards. If no patterns are given, all files are
extracted. @xref{Options}.

cpio @{-i|--extract@} [-bcdfmnrtsuvBSV] [-C bytes] [-E file]

@section Copy-pass mode
In copy-pass mode, cpio copies files from one directory tree to
another, combining the copy-out and copy-in steps without actually
using an archive. It reads the list of files to copy from the
standard input; the directory into which it will copy them is given as
a non-option argument.

@section Options
@table @code
@item -0, --null
Read a list of filenames terminated by a null character, instead of a
newline, so that files whose names contain newlines can be archived.
GNU find is one way to produce a list of null-terminated filenames.
This option may be used in copy-out and copy-pass modes.
@item -a, --reset-access-time
Reset the access times of files after reading them, so
that it does not look like they have just been read.
@item -A, --append
Append to an existing archive. Only works in copy-out
mode. The archive must be a disk file specified with
the -O or -F (--file) option.
@item -b, --swap
Swap both halfwords of words and bytes of halfwords in the data.
Equivalent to -sS. This option may be used in copy-in mode. Use this
option to convert 32-bit integers between big-endian and little-endian
machines.
@item -B
Set the I/O block size to 5120 bytes. Initially the
block size is 512 bytes.
@item --block-size=BLOCK-SIZE
Set the I/O block size to BLOCK-SIZE * 512 bytes.
@item -c
Use the old portable (ASCII) archive format.
@item -C IO-SIZE, --io-size=IO-SIZE
Set the I/O block size to IO-SIZE bytes.
@item -d, --make-directories
Create leading directories where needed.
@item -E FILE, --pattern-file=FILE
Read additional patterns specifying filenames to extract or list from
FILE. The lines of FILE are treated as if they had been non-option
arguments to cpio. This option is used in copy-in mode,
@item -f, --nonmatching
Only copy files that do not match any of the given
patterns.
@item -F, --file=archive
Archive filename to use instead of standard input or output. To use a
tape drive on another machine as the archive, use a filename that starts
with `HOSTNAME:'. The hostname can be preceded by a username and an
`@@' to access the remote tape drive as that user, if you have
permission to do so (typically an entry in that user's `~/.rhosts'
file).
@item --force-local
With -F, -I, or -O, take the archive file name to be a
local file even if it contains a colon, which would
ordinarily indicate a remote host name.
@item -H FORMAT, --format=FORMAT
Use archive format FORMAT. The valid formats are listed below; the same
names are also recognized in all-caps. The default in copy-in mode is
to automatically detect the archive format, and in copy-out mode is
@samp{bin}.
@table @samp
@item bin
The obsolete binary format.
@item odc
The old (POSIX.1) portable format.
@item newc
The new (SVR4) portable format, which supports file systems having more
than 65536 i-nodes.
@item crc
The new (SVR4) portable format with a checksum added.
@item tar
The old tar format.
@item ustar
The POSIX.1 tar format. Also recognizes GNU tar archives, which are
similar but not identical.
@item hpbin
The obsolete binary format used by HPUX's cpio (which stores device
files differently).
@item hpodc
The portable format used by HPUX's cpio (which stores device files
differently).
@end table
@item -i, --extract
Run in copy-in mode.
@xref{Copy-in mode}.
@item -I archive
Archive filename to use instead of standard input. To use a tape drive
on another machine as the archive, use a filename that starts with
`HOSTNAME:'. The hostname can be preceded by a username and an `@@' to
access the remote tape drive as that user, if you have permission to do
so (typically an entry in that user's `~/.rhosts' file).
@item -k
Ignored; for compatibility with other versions of cpio.
@item -l, --link
Link files instead of copying them, when possible.
@item -L, --dereference
Copy the file that a symbolic link points to, rather than the symbolic
link itself.
@item -m, --preserve-modification-time
Retain previous file modification times when creating files.
@item -M MESSAGE, --message=MESSAGE
Print MESSAGE when the end of a volume of the backup media (such as a
tape or a floppy disk) is reached, to prompt the user to insert a new
volume. If MESSAGE contains the string "%d", it is replaced by the
current volume number (starting at 1).
@item -n, --numeric-uid-gid
Show numeric UID and GID instead of translating them into names when using the
@samp{--verbose option}.
@item --no-absolute-filenames
Create all files relative to the current directory in copy-in mode, even
if they have an absolute file name in the archive.
@item --no-preserve-owner
Do not change the ownership of the files; leave them owned by the user
extracting them. This is the default for non-root users, so that users
on System V don't inadvertantly give away files. This option can be
used in copy-in mode and copy-pass mode
@item -o, --create
Run in copy-out mode.
@xref{Copy-out mode}.
@item -O archive
Archive filename to use instead of standard output. To use a tape drive
on another machine as the archive, use a filename that starts with
`HOSTNAME:'. The hostname can be preceded by a username and an `@@' to
access the remote tape drive as that user, if you have permission to do
so (typically an entry in that user's `~/.rhosts' file).
@item --only-verify-crc
Verify the CRC's of each file in the archive, when reading a CRC format
archive. Don't actually extract the files.
@item -p, --pass-through
Run in copy-pass mode.
@xref{Copy-pass mode}.
@item --quiet
Do not print the number of blocks copied.
@item -r, --rename
Interactively rename files.
@item -R [user][:.][group], --owner [user][:.][group]
Set the ownership of all files created to the specified user and/or
group in copy-out and copy-pass modes. Either the user, the group, or
both, must be present. If the group is omitted but the ":" or "."
separator is given, use the given user's login group. Only the
super-user can change files' ownership.
@item -s, --swap-bytes
Swap the bytes of each halfword (pair of bytes) in the files.This option
can be used in copy-in mode.
@item -S, --swap-halfwords
Swap the halfwords of each word (4 bytes) in the files. This option may
be used in copy-in mode.
@item --sparse
Write files with large blocks of zeros as sparse files. This option is
used in copy-out and copy-pass modes.
@item -t, --list
Print a table of contents of the input.
@item -u, --unconditional
Replace all files, without asking whether to replace
existing newer files with older files.
@item -v, --verbose
List the files processed, or with @samp{-t}, give an @samp{ls -l} style
table of contents listing. In a verbose table of contents of a ustar
archive, user and group names in the archive that do not exist on the
local system are replaced by the names that correspond locally to the
numeric UID and GID stored in the archive.
@item -V --dot
Print a @kbd{.} for each file processed.
@item --version
Print the cpio program version number and exit.

@chapter Magnetic Media
@cindex magnetic media
Archives are usually written on removable media--tape cartridges, mag
tapes, or floppy disks.
The amount of data a tape or disk holds depends not only on its size,
but also on how it is formatted. A 2400 foot long reel of mag tape
holds 40 megabytes of data when formated at 1600 bits per inch. The
physically smaller EXABYTE tape cartridge holds 2.3 gigabytes.
Magnetic media are re-usable--once the archive on a tape is no longer
needed, the archive can be erased and the tape or disk used over. Media
quality does deteriorate with use, however. Most tapes or disks should
be disgarded when they begin to produce data errors.
Magnetic media are written and erased using magnetic fields, and should
be protected from such fields to avoid damage to stored data. Sticking
a floppy disk to a filing cabinet using a magnet is probably not a good
idea.

/* The man page rmt(8) for /etc/rmt documents the remote mag tape
protocol which rdump and rrestore use. Unfortunately, the man
page is *WRONG*. The author of the routines I'm including originally
wrote his code just based on the man page, and it didn't work, so he
went to the rdump source to figure out why. The only thing he had to
change was to check for the 'F' return code in addition to the 'E',
and to separate the various arguments with \n instead of a space. I
personally don't think that this is much of a problem, but I wanted to
point it out. -- Arnold Robbins
Originally written by Jeff Lee, modified some by Arnold Robbins.
Redone as a library that can replace open, read, write, etc., by
Fred Fish, with some additional work by Arnold Robbins.
Modified to make all rmtXXX calls into macros for speed by Jay Fenlason.
