# To install on versions prior to BSD 4.4 the following may have to be
# defined with CFLAGS +=
#
# -DNET2_STAT Use NET2 or older stat structure. The version of the
# stat structure is easily determined by looking at the
# basic type of an off_t (often defined in the file:
# /usr/include/sys/types.h). If off_t is a long (and is
# NOT A quad) then you must define NET2_STAT.
# This define is important, as if you do have a quad_t
# off_t and define NET2_STAT, pax will compile but will
# NOT RUN PROPERLY.
#
# -DNET2_FTS Use the older NET2 fts. To identify the version,
# examine the file: /usr/include/fts.h. If FTS_COMFOLLOW
# is not defined then you must define NET2_FTS.
# Pax may not compile if this not (un)defined properly.
#
# -DNET2_REGEX Use the older regexp.h not regex.h. The regex version
# is determined by looking at the value returned by
# regexec() (man 3 regexec). If regexec return a 1 for
# success (and NOT a 0 for success) you have the older
# regex routines and must define NET2_REGEX.
# Pax may not compile if this not (un)defined properly.

.Pp
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.
.Pp
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
or error,
.Nm
may have only partially created the archive which may violate the
specific archive format specification.

.Sh DESCRIPTION
The
.Nm
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 .
.El
.Pp
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
Stop after first error.
.It Fl f Ar archive
Filename where the archive is stored.
Defaults to
.Pa /dev/sa0 .
.It Fl h
Follow symbolic links as if they were normal files
or directories.
.It Fl j
Compress archives using
.Xr bzip2 1 .
.It Fl m
Do not preserve modification time.
.It Fl O
Write old-style
.Pq non- Ns Tn POSIX
archives.
.It Fl o
Do not write directory information that the older (V7) style
.Nm
is unable to decode.
This implies the
.Fl O
flag.
.It Fl p
Preserve user and group ID as well as file mode regardless of
the current
.Xr umask 2 .
The setuid and setgid bits are only preserved if the user is
the superuser.
Only meaningful in conjunction with the
.Fl x
flag.
.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
.Ar file
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 L
Follow all symlinks.
.It Fl P
Do not strip leading slashes
.Pq Ql /
from pathnames.
The default is to strip leading slashes.
.It Fl I Ar file
This is a positional argument which reads the names of files to
archive or extract from the given file, one per line.
.It Fl X
Do not cross mount points in the file system.
.It Fl Z
Compress archive using
.Xr compress 1 .
.El
.Pp
The options
.Op Fl 014578
can be used to select one of the compiled-in backup devices,
.Pa /dev/rst Ns Ar N .
.Sh ENVIRONMENT
.Bl -tag -width TMPDIR
.It Ev TMPDIR
Path in which to store temporary files.
.It Ev TAPE
Default tape device to use instead of
.Pa /dev/sa0 .
.El
.Sh FILES
.Bl -tag -width "/dev/sa0"
.It Pa /dev/sa0
default archive name
.El
.Sh EXIT STATUS
The
.Nm
utility will exit with one of the following values:
.Bl -tag -width 2n
.It 0
All files were processed successfully.
.It 1
An error occurred.
.El
.Pp
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.
.Pp
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
or error,
.Nm
may have only partially created the archive which may violate the
specific archive format specification.
.Sh COMPATIBILITY
The
.Fl L
flag is not portable to other versions of
.Nm
where it may have a different meaning.
