.Sh DESCRIPTION
The
.Nm
utility creates and maintains groups of files combined into an archive.
Once an archive has been created, new files can be added and existing
files can be extracted, deleted, or replaced.
.Pp
Files are named in the archive by a single component, i.e., if a file
referenced by a path containing a slash (``/'') is archived it will be
named by the last component of that path.
When matching paths listed on the command line against file names stored
in the archive, only the last component of the path will be compared.
.Pp
All informational and error messages use the path listed on the command
line, if any was specified; otherwise the name in the archive is used.
If multiple files in the archive have the same name, and paths are listed
on the command line to ``select'' archive files for an operation, only the
.Em first
file with a matching name will be selected.
.Pp
The normal use of
.Nm
is for the creation and maintenance of libraries suitable for use with
the loader (see
.Xr ld 1 )
although it is not restricted to this purpose.
.Pp
The options are as follows:
.Bl -tag -width indent
.It Fl a
A positioning modifier used with the options
.Fl r
and
.Fl m .
The files are entered or moved
.Em after
the archive member
.Ar position ,
which must be specified.
.It Fl b
A positioning modifier used with the options
.Fl r
and
.Fl m .
The files are entered or moved
.Em before
the archive member
.Ar position ,
which must be specified.
.It Fl c
Whenever an archive is created, an informational message to that effect
is written to standard error.
If the
.Fl c
option is specified,
.Nm
creates the archive silently.
.It Fl d
Delete the specified archive files.
.It Fl i
Identical to the
.Fl b
option.
.It Fl m
Move the specified archive files within the archive.
If one of the options
.Fl a ,
.Fl b
or
.Fl i
is specified, the files are moved
before or after the
.Ar position
file in the archive.
If none of those options are specified, the files are moved
to the end of the archive.
.It Fl o
Set the access and modification times of extracted files to the
modification time of the file when it was entered into the archive.
This will fail if the user is not the owner of the extracted file
or the super-user.
.It Fl p
Write the contents of the specified archive files to the standard output.
If no files are specified, the contents of all the files in the archive
are written in the order they appear in the archive.
.It Fl q
(Quickly) append the specified files to the archive.
If the archive does not exist a new archive file is created.
Much faster than the
.Fl r
option, when creating a large archive
piece-by-piece, as no checking is done to see if the files already
exist in the archive.
.It Fl r
Replace or add the specified files to the archive.
If the archive does not exist a new archive file is created.
Files that replace existing files do not change the order of the files
within the archive.
New files are appended to the archive unless one of the options
.Fl a ,
.Fl b
or
.Fl i
is specified.
.It Fl T
Select and/or name archive members using only the first fifteen characters
of the archive member or command line file name.
The historic archive format had sixteen bytes for the name, but some
historic archiver and loader implementations were unable to handle names
that used the entire space.
This means that file names that are not unique in their first fifteen
characters can subsequently be confused.
A warning message is printed to the standard error output if any file
names are truncated.
(See
.Xr ar 5
for more information.)
.It Fl t
List the specified files in the order in which they appear in the archive,
each on a separate line.
If no files are specified, all files in the archive are listed.
.It Fl u
Update files.
When used with the
.Fl r
option, files in the archive will be replaced
only if the disk file has a newer modification time than the file in
the archive.
When used with the
.Fl x
option, files in the archive will be extracted
only if the archive file has a newer modification time than the file
on disk.
.It Fl v
Provide verbose output.
When used with the
.Fl d ,
.Fl m ,
.Fl q
or
.Fl x
options,
.Nm
gives a file-by-file description of the archive modification.
This description consists of three, white-space separated fields: the
option letter, a dash (``-'') and the file name.
When used with the
.Fl r
option,
.Nm
displays the description as above, but the initial letter is an ``a'' if
the file is added to the archive and an ``r'' if the file replaces a file
already in the archive.
.Pp
When used with the
.Fl p
option,
the name of each printed file,
enclosed in less-than (``<'') and greater-than (``>'') characters,
is written to the standard output before
the contents of the file;
it is preceded by a single newline character, and
followed by two newline characters.
.Pp
When used with the
.Fl t
option,
.Nm
displays an ``ls -l'' style listing of information about the members of
the archive.
This listing consists of eight, white-space separated fields:
the file permissions (see
.Xr strmode 3 ) ,
the decimal user and group ID's, separated by a single slash (``/''),
the file size (in bytes), the file modification time (in the
.Xr date 1
format ``%b %e %H:%M %Y''), and the name of the file.
.It Fl x
Extract the specified archive members into the files named by the command
line arguments.
If no members are specified, all the members of the archive are extracted into
the current directory.
.Pp
If the file does not exist, it is created; if it does exist, the owner
and group will be unchanged.
The file access and modification times are the time of the extraction
(but see the
.Fl o
option).
The file permissions will be set to those of the file when it was entered
into the archive; this will fail if the user is not the owner of the
extracted file or the super-user.

.Sh COMPATIBILITY
By default,
.Nm
writes archives that may be incompatible with historic archives, as
the format used for storing archive members with names longer than
fifteen characters has changed.
This implementation of
.Nm
is backward compatible with previous versions of
.Nm
in that it can read and write (using the
.Fl T
option) historic archives.
The
.Fl T
option is provided for compatibility only, and will be deleted
in a future release.
See
.Xr ar 5
for more information.

utility is expected to offer a superset of the

.Sh NAME
.Nm ar
.Nd archive (library) file format
.Sh SYNOPSIS
.In ar.h
.Sh DESCRIPTION
The archive command
.Nm
combines several files into one.
Archives are mainly used as libraries of object files intended to be
loaded using the link-editor
.Xr ld 1 .
.Pp
A file created with
.Nm
begins with the ``magic'' string "!<arch>\en".
The rest of the archive is made up of objects, each of which is composed
of a header for a file, a possible file name, and the file contents.
The header is portable between machine architectures, and, if the file
contents are printable, the archive is itself printable.
.Pp
The header is made up of six variable length
.Tn ASCII
fields, followed by a
two character trailer.
The fields are the object name (16 characters), the file last modification
time (12 characters), the user and group id's (each 6 characters), the file
mode (8 characters) and the file size (10 characters).
All numeric fields are in decimal, except for the file mode which is in
octal.
.Pp
The modification time is the file
.Fa st_mtime
field, i.e.,
.Dv CUT
seconds since
the epoch.
The user and group id's are the file
.Fa st_uid
and
.Fa st_gid
fields.
The file mode is the file
.Fa st_mode
field.
The file size is the file
.Fa st_size
field.
The two-byte trailer is the string "\`\en".
.Pp
Only the name field has any provision for overflow.
If any file name is more than 16 characters in length or contains an
embedded space, the string "#1/" followed by the
.Tn ASCII
length of the
name is written in the name field.
The file size (stored in the archive header) is incremented by the length
of the name.
The name is then written immediately following the archive header.
.Pp
Any unused characters in any of these fields are written as space
characters.
If any fields are their particular maximum number of characters in
length, there will be no separation between the fields.
.Pp
Objects in the archive are always an even number of bytes long; files
which are an odd number of bytes long are padded with a newline (``\en'')

.Sh HISTORY
There have been at least four
.Nm
formats.
The first was denoted by the leading ``magic'' number 0177555 (stored as
type int).
These archives were almost certainly created on a 16-bit machine, and
contain headers made up of five fields.
The fields are the object name (8 characters), the file last modification
time (type long), the user id (type char), the file mode (type char) and
the file size (type unsigned int).
Files were padded to an even number of bytes.
.Pp
The second was denoted by the leading ``magic'' number 0177545 (stored as
type int).
These archives may have been created on either 16 or 32-bit machines, and
contain headers made up of six fields.
The fields are the object name (14 characters), the file last modification
time (type long), the user and group id's (each type char), the file mode
(type int) and the file size (type long).
Files were padded to an even number of bytes.
.\" For more information on converting from this format see
.\" .Xr arcv 8 .
.Pp
The current archive format (without support for long character names and
names with embedded spaces) was introduced in
.Bx 4.0 .
The headers were the same as the current format, with the exception that
names longer than 16 characters were truncated, and names with embedded
spaces (and often trailing spaces) were not supported.
It has been extended for these reasons,
as described above.
This format first appeared in
.Bx 4.4 .
.Sh COMPATIBILITY
No archive format is currently specified by any standard.
.At V
has historically distributed archives in a different format from
all of the above.

.Nd display name list (symbol table)
.Sh SYNOPSIS
.Nm
.Op Fl agnoprtuwW
.Op Ar
.Sh DESCRIPTION
The symbol table (name list) of each object in
.Ar file Ns (s)
is displayed.
If a library (archive) is given,
.Nm
displays a list for each
object archive member.
If
.Ar file
is not present,
.Nm
searches for the file
.Pa a.out
and if present, displays the symbol
table for
.Pa a.out .
.Pp
The following options are available:
.Bl -tag -width indent
.It Fl a
Display symbol table entries inserted for use by debuggers.
.It Fl g
Restrict display to external (global) symbols.
.It Fl n
Present results in numerical order.
.It Fl o
Display full path or library name of object on every line.
.It Fl p
Do not sort at all.
.It Fl r
Reverse order sort.
.It Fl t
Output in tabular format more suitable for other programs digestive system.
.It Fl u
Display undefined symbols only.
.It Fl w
Warn about non-object archive members.
Normally, nm will silently ignore all archive members which are not
object files.
.It Fl W
Include an extra column in the output with a ``W'' indicating weak symbols.
.El
.Pp
Each symbol name is preceded by its value (a blank field if the symbol
is undefined) and one of the following letters:
.Pp
.Bl -tag -width Ds -compact -offset indent
.It Fl
debugger symbol table entries (see the
.Fl a
option)
.It Li A
absolute
.It Li B
bss segment symbol
.It Li C
common symbol
.It Li D
data segment symbol
.It Li f
file name
.It Li I
indirect reference symbol
.It Li T
text segment symbol
.It Li U
undefined
.It Li W
warn if next symbol is referenced
.El
.Pp
If the symbol is local (non-external) the type letter is in lower case.
The output is sorted alphabetically.
.Sh KEYWORDS
The following is a complete list of keywords and their meaning.
The keyword is uppercase for external, lowercase for internal symbols.
Only uppercase keywords are shown here.

.Sh SYNOPSIS
.Nm
.Op Fl afo
.Op Fl n Ar number
.Op Ar
.Sh DESCRIPTION
The
.Nm
utility
displays the sequences of printable characters in each of the specified
files, or in the standard input, by default.
By default, a sequence must be at least four characters in length
before being displayed.
.Pp
The options are as follows:
.Bl -tag -width Ds
.It Fl a
By default,
.Nm
only searches the text and data segments of object files.
The
.Fl a
option causes
.Nm
to search the entire object file.
.It Fl f
Each string is preceded by the name of the file
in which it was found.
.It Fl n
Specifies the minimum number of characters in a sequence to be
.Ar number ,
instead of four.
.It Fl o
Each string is preceded by its decimal offset in the
file.
.El
.Pp
The
.Nm
utility is useful for identifying random binaries, among other things.
.Sh SEE ALSO
.Xr hexdump 1
.Sh BUGS
The algorithm for identifying strings is extremely primitive.
In particular, machine code instructions on certain architectures
can resemble sequences of ASCII bytes, which
will fool the algorithm.
.Sh COMPATIBILITY
Historic implementations of
.Nm
only search the initialized data portion of the object file.
This was reasonable as strings were normally stored there.
Given new compiler technology which installs strings in the
text portion of the object file, the default behavior was
changed.
.Sh HISTORY
The
.Nm
command appeared in
.Bx 3.0 .
