|

The

command creates, adds files to, or extracts files from an
|
|
||||||
archive file in

|
||||||
.Nm
|
|

format.
|
|
||||||
A
|
|
||||||
.Nm
|
|
||||||
archive is often stored on a magnetic tape, but can be
|
|
||||||
stored equally well on a floppy, CD-ROM, or in a regular disk file.
|
|
||||||
.Pp
|
|
||||||
One of the following flags must be present:
|
|
||||||
.Bl -tag -width indent
|
|
||||||
.It Fl c
|
|
||||||
Create new archive, or overwrite an existing archive,
|
|
||||||
adding the specified files to it.
|
|
||||||
.It Fl r
|
|
||||||
Append the named new files to existing archive.
|
|
||||||
Note that this will only work on media on which an end-of-file mark
|
|
||||||
can be overwritten.
|
|
||||||
.It Fl t
|
|
||||||
List contents of archive.
|
|
||||||
If any files are named on the
|
|
||||||
command line, only those files will be listed.
|
|
||||||
.It Fl u
|
|
||||||
Alias for
|
|
||||||
.Fl r .
|
|
||||||
.It Fl x
|
|
||||||
Extract files from archive.
|
|
||||||
If any files are named on the
|
|
||||||
command line, only those files will be extracted from the
|
|
||||||
archive.
|
|
||||||
If more than one copy of a file exists in the
|
|
||||||
archive, later copies will overwrite earlier copies during
|
|
||||||
extraction.
|
|
||||||
The file mode and modification time are preserved
|
|
||||||
if possible.
|
|
||||||
The file mode is subject to modification by the
|
|
||||||
.Xr umask 2 .
|
|

|
|
||||||

|
|

In addition to the flags mentioned above, any of the following

flags may be used:
|
|
||||||
.Bl -tag -width indent
|
|
||||||
.It Fl b Ar "blocking factor"
|
|
||||||
Set blocking factor to use for the archive, with 512 byte blocks.
|
|
||||||
The default is 20, the maximum is 126.
|
|
||||||
Archives with a blocking factor larger 63 violate the
|
|
||||||
.Tn POSIX
|
|
||||||
standard and will not be portable to all systems.
|
|
||||||
.It Fl e
|

Do not write directory information that the older (V7) style
|

This implies the

flag.
|
|
||||||
.It Fl p
|
|
||||||
Preserve user and group ID as well as file mode regardless of
|
|
||||||
the current
|
|

The setuid and setgid bits are only preserved if the user is

the superuser.

.It Fl q
|
|
||||||
Select the first archive member that matches each
|
|
||||||
.Ar pattern
|
|
||||||
operand.
|
|
||||||
No more than one archive member is matched for each
|
|
||||||
.Ar pattern .
|
|
||||||
When members of type directory are matched, the file hierarchy rooted at that
|
|

directory is also matched.

.It Fl s Ar replstr
|
|
||||||
Modify the file or archive member names specified by the
|
|
||||||
.Ar pattern
|

or

operands according to the substitution expression
|
|
||||||
.Ar replstr ,
|
|
||||||
using the syntax of the
|
|
||||||
.Xr ed 1
|
|
||||||
utility regular expressions.
|
|
||||||
The format of these regular expressions are:
|
|
||||||
.Dl /old/new/[gp]
|
|
||||||
As in
|
|
||||||
.Xr ed 1 ,
|
|
||||||
.Cm old
|
|
||||||
is a basic regular expression and
|
|
||||||
.Cm new
|
|
||||||
can contain an ampersand
|
|
||||||
.Pq Ql & ,
|
|
||||||
.Li \e Ns Ar n
|
|
||||||
(where
|
|
||||||
.Ar n
|
|
||||||
is a digit) back-references,
|
|
||||||
or subexpression matching.
|
|
||||||
The
|
|
||||||
.Cm old
|
|
||||||
string may also contain newline characters.
|
|
||||||
Any non-null character can be used as a delimiter
|
|
||||||
.Ql ( /
|
|
||||||
is shown here).
|
|
||||||
Multiple
|
|
||||||
.Fl s
|
|
||||||
expressions can be specified.
|
|
||||||
The expressions are applied in the order they are specified on the
|
|
||||||
command line, terminating with the first successful substitution.
|
|
||||||
The optional trailing
|
|
||||||
.Cm g
|
|
||||||
continues to apply the substitution expression to the pathname substring
|
|
||||||
which starts with the first character following the end of the last successful
|
|
||||||
substitution.
|
|
||||||
The first unsuccessful substitution stops the operation of the
|
|
||||||
.Cm g
|
|
||||||
option.
|
|
||||||
The optional trailing
|
|
||||||
.Cm p
|
|
||||||
will cause the final result of a successful substitution to be written to
|
|
||||||
standard error
|
|
||||||
in the following format:
|
|
||||||
.Pp
|
|
||||||
.Dl <original pathname> >> <new pathname>
|
|
||||||
.Pp
|
|
||||||
File or archive member names that substitute to the empty string
|
|
||||||
are not selected and will be skipped.

|
||||||
.It Fl v
|
|
||||||
Verbose operation mode.
|
|
||||||
.It Fl w
|
|
||||||
Interactively rename files.
|
|
||||||
This option causes
|
|
||||||
.Nm
|
|
||||||
to prompt the user for the filename to use when storing or
|
|
||||||
extracting files in an archive.
|
|
||||||
.It Fl y
|
|
||||||
Compress archives using
|
|
||||||
.Xr bzip2 1 .
|
|
||||||
.It Fl z
|
|
||||||
Compress archive using
|
|
||||||
.Xr gzip 1 .
|
|
||||||
.It Fl C Ar directory
|
|
||||||
This is a positional argument which sets the working directory for the
|
|
||||||
following files.
|
|
||||||
When extracting, files will be extracted into
|
|
||||||
the specified directory; when creating, the specified files will be matched
|
|
||||||
from the directory.
|
|
||||||
.It Fl H
|
|
||||||
Follow symlinks given on command line only.
|

.It Fl I Ar file

.Bl -tag -width 2n
|
|

All files were processed successfully.

An error occurred.

|

Whenever
|
|
||||||
.Nm
|
|
||||||
cannot create a file or a link when extracting an archive or cannot
|
|
||||||
find a file while writing an archive, or cannot preserve the user
|
|
||||||
ID, group ID, file mode, or access and modification times when the
|
|
||||||
.Fl p
|
|
||||||
option is specified, a diagnostic message is written to standard
|
|
||||||
error and a non-zero exit value will be returned, but processing
|
|
||||||
will continue.
|
|
||||||
In the case where
|
|
||||||
.Nm
|
|
||||||
cannot create a link to a file,
|
|
||||||
.Nm
|
|
||||||
will not create a second copy of the file.

|
|

If the extraction of a file from an archive is prematurely terminated
|
|

by a signal or error,
|

.Nm
|
|
||||||
may have only partially extracted the file the user wanted.
|
|
||||||
Additionally, the file modes of extracted files and directories may
|
|
||||||
have incorrect file bits, and the modification and access times may
|
|
||||||
be wrong.
|

.Pp
|
|

If the creation of an archive is prematurely terminated by a signal
|

may have only partially created the archive which may violate the

The
