.Sh NAME
.Nm cp
.Nd copy files
.Sh SYNOPSIS
.Nm
.Oo
.Fl R
.Op Fl H | Fl L | Fl P
.Oc
.Op Fl f | i
.Op Fl alNpv
.Ar source_file target_file
.Nm cp
.Oo
.Fl R
.Op Fl H | Fl L | Fl P
.Oc
.Op Fl f | i
.Op Fl alNpv
.Ar source_file ... target_directory
.Sh DESCRIPTION
In the first synopsis form, the
.Nm
utility copies the contents of the
.Ar source_file
to the
.Ar target_file .
In the second synopsis form,
the contents of each named
.Ar source_file
is copied to the destination
.Ar target_directory .
The names of the files themselves are not changed.
If
.Nm
detects an attempt to copy a file to itself, the copy will fail.
.Pp
The following options are available:
.Bl -tag -width flag
.It Fl a
Archive mode.
Same as
.Fl RpP .
.It Fl f
For each existing destination pathname, attempt to overwrite it.
If permissions do not allow copy to succeed, remove it and create a new
file, without prompting for confirmation.
(The
.Fl i
option is ignored if the
.Fl f
option is specified.)
.It Fl H
If the
.Fl R
option is specified, symbolic links on the command line are followed.
(Symbolic links encountered in the tree traversal are not followed.)
.It Fl i
Causes
.Nm
to write a prompt to the standard error output before copying a file
that would overwrite an existing file.
If the response from the standard input begins with the character
.Sq Li y ,
the file copy is attempted.
.It Fl L
If the
.Fl R
option is specified, all symbolic links are followed.
.It Fl l
Create hard links to regular files in a hierarchy instead of copying.
.It Fl N
When used with
.Fl p ,
don't copy file flags.
.It Fl P
No symbolic links are followed.
This is the default.
.It Fl p
Causes
.Nm
to preserve in the copy as many of the modification time, access time,
file flags, file mode, user ID, group ID, and extended attributes,
as allowed by permissions.
.Pp
If the user ID and group ID cannot be preserved, no error message
is displayed and the exit value is not altered.
.Pp
If the source file has its set user ID bit on and the user ID cannot
be preserved, the set user ID bit is not preserved
in the copy's permissions.
If the source file has its set group ID bit on and the group ID cannot
be preserved, the set group ID bit is not preserved
in the copy's permissions.
If the source file has both its set user ID and set group ID bits on,
and either the user ID or group ID cannot be preserved, neither
the set user ID or set group ID bits are preserved in the copy's
permissions.
.Pp
Extended attributes from all accessible namespaces are copied;
others are ignored.
If an error occurs during this copy, a message is displayed and
.Nm
skips the other extended attributes for that file.
.It Fl R
If
.Ar source_file
designates a directory,
.Nm
copies the directory and the entire subtree connected at that point.
This option also causes symbolic links to be copied, rather than
followed, and for
.Nm
to create special files rather than copying them as normal files.
Created directories have the same mode as the corresponding source
directory, unmodified by the process's umask.
.Pp
Note that
.Nm
copies hard linked files as separate files.
If you need to preserve hard links, consider using a utility like
.Xr pax 1
instead.
.It Fl v
Causes
.Nm
to be verbose, showing files as they are copied.
.El
.Pp
For each destination file that already exists, its contents are
overwritten if permissions allow, but its mode, user ID, and group
ID are unchanged.
.Pp
In the second synopsis form,
.Ar target_directory
must exist unless there is only one named
.Ar source_file
which is a directory and the
.Fl R
flag is specified.
.Pp
If the destination file does not exist, the mode of the source file is
used as modified by the file mode creation mask
.Ic ( umask ,
see
.Xr csh 1 ) .
If the source file has its set user ID bit on, that bit is removed
unless both the source file and the destination file are owned by the
same user.
If the source file has its set group ID bit on, that bit is removed
unless both the source file and the destination file are in the same
group and the user is a member of that group.
If both the set user ID and set group ID bits are set, all of the above
conditions must be fulfilled or both bits are removed.
.Pp
Appropriate permissions are required for file creation or overwriting.
.Pp
Symbolic links are always followed unless the
.Fl R
flag is set, in which case symbolic links are not followed, by default.
The
.Fl H
or
.Fl L
flags (in conjunction with the
.Fl R
flag), as well as the
.Fl P
flag cause symbolic links to be followed as described above.
The
.Fl H
and
.Fl L
options are ignored unless the
.Fl R
option is specified.
In addition, these options override each other and the
command's actions are determined by the last one specified.
The default is as if the
.Fl P
option had been specified.
.Sh EXIT STATUS
.Ex -std cp
.Sh COMPATIBILITY
Historic versions of the
.Nm
utility had a
.Fl r
option.
This implementation supports that option, however, its use is strongly
discouraged, as it does not correctly copy special files, symbolic links,
or FIFOs.
.Sh SEE ALSO
.Xr mv 1 ,
.Xr pax 1 ,
.Xr rcp 1 ,
.Xr umask 2 ,
.Xr fts 3 ,
.Xr symlink 7
.Sh STANDARDS
The
.Nm
utility is expected to be
.St -p1003.2
compatible.
.Pp
The
.Fl a
and
.Fl l
flags are non-standard extensions.
They are intended to be compatible with the same options which
other implementations, namely GNU coreutils and
.Fx ,
of this utility have.
.Pp
The
.Fl v
option is an extension to
.St -p1003.2 .
.Sh HISTORY
A
.Nm
utility appeared in
.At v1 .

.Dt DATE 1
.Os
.Sh NAME
.Nm date
.Nd display or set date and time
.Sh SYNOPSIS
.Nm
.Op Fl ajnu
.Op Fl d Ar date
.Op Fl r Ar seconds
.Op Cm + Ns Ar format
.Sm off
.Oo Oo Oo Oo Oo Oo
.Ar CC Oc
.Ar yy Oc
.Ar mm Oc
.Ar dd Oc
.Ar HH Oc Ar MM Oo
.Li \&. Ar SS Oc Oc
.Sm on
.Sh DESCRIPTION
.Nm
displays the current date and time when invoked without arguments.
Providing arguments will format the date and time in a user-defined
way or set the date.
Only the superuser may set the date.
.Pp
The options are as follows:
.Bl -tag -width Ds
.It Fl a
Use
.Xr adjtime 2
to change the local system time slowly,
maintaining it as a monotonically increasing function.
.Fl a
implies
.Fl n .
.It Fl d Ar date
Parse the provided human-described date and time and display the result without
actually changing the system clock.
(See
.Xr parsedate 3
for examples.)
.It Fl j
Parse the provided canonical representation of date and time (described below)
and display the result without actually changing the system clock.
.It Fl n
The utility
.Xr timed 8
is used to synchronize the clocks on groups of machines.
By default, if
.Xr timed 8
is running,
.Nm
will set the time on all of the machines in the local group.
The
.Fl n
option stops
.Nm
from setting the time for other than the current machine.
.It Fl r Ar seconds
Print out the date and time that is
.Ar seconds
from the Epoch.
.It Fl u
Display or set the date in
.Tn UTC
(universal) time.
.El
.Pp
An operand with a leading plus
.Pq Cm +
sign signals a user-defined format
string which specifies the format in which to display the date and time.
The format string may contain any of the conversion specifications described
in the
.Xr strftime 3
manual page, as well as any arbitrary text.
A \*[Lt]newline\*[Gt] character is always output after the characters
specified by the format string.
The format string for the default display is:
.Bd -literal -offset indent
%a %b %e %H:%M:%S %Z %Y
.Ed
.Pp
If an operand does not have a leading plus sign, it is interpreted as
a value for setting the system's notion of the current date and time.
The canonical representation for setting the date and time is:
.Pp
.Bl -tag -width Ds -compact -offset indent
.It Ar CC
The first two digits of the year (the century).
.It Ar yy
The second two digits of the year.
If
.Ar yy
is specified, but
.Ar CC
is not, a value for
.Ar yy
between 69 and 99 results in a
.Ar CC
value of 19.
Otherwise, a
.Ar CC
value of 20 is used.
.It Ar mm
The month of the year, from 01 to 12.
.It Ar dd
The day of the month, from 01 to 31.
.It Ar HH
The hour of the day, from 00 to 23.
.It Ar MM
The minute of the hour, from 00 to 59.
.It Ar SS
The second of the minute, from 00 to 60.
.El
.Pp
Everything but the minutes is optional.
.Pp
Time changes for Daylight Saving and Standard Time and leap seconds
and years are handled automatically.
.Sh ENVIRONMENT
The following environment variables affect the execution of
.Nm :
.Bl -tag -width iTZ
.It Ev TZ
The timezone to use when displaying dates.
See
.Xr environ 7
for more information.
.El
.Sh FILES
.Bl -tag -width /var/log/messages -compact
.It Pa /etc/localtime
Symlink pointing to system's default timezone information file in
.Pa /usr/share/zoneinfo
directory.
.It Pa /var/log/wtmp
A record of date resets and time changes.
.It Pa /var/log/messages
A record of the user setting the time.
.El
.Sh EXAMPLES
The command:
.Bd -literal -offset indent
date '+DATE: %m/%d/%y%nTIME: %H:%M:%S'
.Ed
.Pp
will display:
.Bd -literal -offset indent
DATE: 11/21/87
TIME: 13:36:16
.Ed
.Pp
The command:
.Bd -literal -offset indent
date 8506131627
.Ed
.Pp
sets the date to
.Dq Li "June 13, 1985, 4:27 PM" .
.Pp
The command:
.Bd -literal -offset indent
date 1432
.Ed
.Pp
sets the time to
.Li "2:32 PM" ,
without modifying the date.
.Sh DIAGNOSTICS
Exit status is 0 on success, 1 if unable to set the date, and 2
if able to set the local date, but unable to set it globally.
.Pp
Occasionally, when
.Xr timed 8
synchronizes the time on many hosts, the setting of a new time value may
require more than a few seconds.
On these occasions,
.Nm
prints:
.Ql Network time being set .
The message
.Ql Communication error with
.Xr timed 8
occurs when the communication
between
.Nm
and
.Xr timed 8
fails.

.Sh NAME
.Nm mkdir
.Nd make directories
.Sh SYNOPSIS
.Nm
.Op Fl p
.Op Fl m Ar mode
.Ar directory_name ...
.Sh DESCRIPTION
.Nm
creates the directories named as operands, in the order specified,
using mode
.Li rwxrwxrwx (\&0777)
as modified by the current
.Xr umask 2 .
.Pp
The options are as follows:
.Pp
.Bl -tag -width indent
.It Fl m
Set the file permission bits of the final created directory to
the specified mode.
The mode argument can be in any of the formats specified to the
.Xr chmod 1
utility.
If a symbolic mode is specified, the operation characters
.Dq +
and
.Dq -
are interpreted relative to an initial mode of
.Dq a=rwx .
.It Fl p
Create intermediate directories as required.
If this option is not specified, the full path prefix of each
operand must already exist.
Intermediate directories are created with permission bits of
.Li rwxrwxrwx (\&0777)
as modified by the current umask, plus write and search
permission for the owner.
Do not consider it an error if the argument directory already exists.
.El
.Pp
The user must have write permission in the parent directory.
.Sh EXIT STATUS
.Nm
exits 0 if successful, and \*[Gt]0 if an error occurred.
.Sh SEE ALSO
.Xr chmod 1 ,
.Xr rmdir 1 ,
.Xr mkdir 2 ,
.Xr umask 2
.Sh STANDARDS
The
.Nm
utility is expected to be

.Sh DESCRIPTION
The
.Nm
command copies files to and from a
.Nm
archive.
If the archive is of the form:
.Ar [[user@]host:]file
then the archive will be processed using
.Xr rmt 8 .
.Pp
The options are as follows:
.Bl -tag -width Ds
.It Fl o , Fl Fl create
Create an archive.
Reads the list of files to store in the
archive from standard input, and writes the archive on standard
output.
.Bl -tag -width Ds
.It Fl a , Fl Fl reset-access-time
Reset the access times on files that have been copied to the
archive.
.It Fl A , Fl Fl append
Append to the specified archive.
.It Fl B
Set block size of output to 5120 bytes.
.It Fl c
Use ASCII format for
.Nm
header for portability.
.It Fl C Ar bytes
Set the block size of output to
.Ar bytes .
.It Fl F Ar archive
.It Fl O Ar archive
Use the specified file name as the archive to write to.
.It Fl H Ar format
Write the archive in the specified format.
Recognized formats are:
.Pp
.Bl -tag -width sv4cpio -compact
.It Ar bcpio
Old binary
.Nm
format.
.It Ar cpio

.El
.It Fl L
Follow symbolic links.
.It Fl v
Be verbose about operations.
List filenames as they are written to the archive.
.It Fl Fl xz
Compress/decompress archive using
.Xr xz 1
format.
.It Fl Z
Compress archive using
.Xr compress 1
format.
.It Fl z
Compress/decompress archive using
.Xr gzip 1
format.
.El
.It Fl i , Fl Fl extract
Restore files from an archive.
Reads the archive file from
standard input and extracts files matching the
.Ar patterns
that were specified on the command line.
.Bl -tag -width Ds
.It Fl b
Do byte and word swapping after reading in data from the
archive, for restoring archives created on systems with
a different byte order.
.It Fl B
Set the block size of the archive being read to 5120 bytes.
.It Fl c
Expect the archive headers to be in ASCII format.
.It Fl C Ar bytes
Read archive written with a block size of
.Ar bytes .
.It Fl d , Fl Fl make-directories
Create any intermediate directories as needed during
restore.
.It Fl E Ar file , Fl Fl pattern-file Ar file
Read list of file name patterns to extract or list from
.Ar file .
.It Fl f , Fl Fl nonmatching
Restore all files except those matching the
.Ar patterns
given on the command line.
.It Fl F Ar archive , Fl Fl file Ar archive
.It Fl I Ar archive
Use the specified file as the input for the archive.
.It Fl H Ar format , Fl Fl format Ar format
Read an archive of the specified format.
Recognized formats are:
.Pp

Restore modification times on files.
.It Fl r , Fl Fl rename
Rename restored files interactively.
.It Fl s
Swap bytes after reading data from the archive.
.It Fl S , Fl Fl swap-halfwords
Swap words after reading data from the archive.
.It Fl t , Fl Fl list
Only list the contents of the archive, no files or
directories will be created.
.It Fl u , Fl Fl unconditional
Overwrite files even when the file in the archive is
older than the one that will be overwritten.
.It Fl v , Fl Fl verbose
Be verbose about operations.
List filenames as they are copied in from the archive.
.It Fl z
Uncompress archive using
.Xr gzip 1
format.
.It Fl Z
Uncompress archive using
.Xr compress 1
format.
.It Fl 6
Process old-style
.Nm
format archives.
.El
.It Fl p , Fl Fl pass-through
Copy files from one location to another in a single pass.
The list of files to copy are read from standard input and
written out to a directory relative to the specified
.Ar directory
argument.
.Bl -tag -width Ds
.It Fl a
Reset the access times on files that have been copied.
.It Fl d
Create any intermediate directories as needed to write
the files at the new location.
.It Fl l , Fl Fl link
When possible, link files rather than creating an
extra copy.
.It Fl L , Fl Fl dereference
Follow symbolic links.
.It Fl m , Fl Fl preserve-modification-time
Restore modification times on files.
.It Fl u , Fl Fl unconditional
Overwrite files even when the original file being copied is
older than the one that will be overwritten.
.It Fl v , Fl Fl verbose
Be verbose about operations.
List filenames as they are copied.
.It Fl Fl force-local
Do not interpret filenames that contain a
.Sq \&:
as remote files.
.It Fl Fl insecure
Normally
.Nm
ignores filenames that contain
.Dq ..
as a path component.
With this option, files that contain
.Dq ..
can be processed.
.El
.El
.Sh EXIT STATUS
.Nm
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.

/*
* PAX - Portable Archive Interchange
*
* A utility to read, write, and write lists of the members of archive
* files and copy directory hierarchies. A variety of archive formats
* are supported (some are described in POSIX 1003.1 10.1):
*
* ustar - 10.1.1 extended tar interchange format
* cpio - 10.1.2 extended cpio interchange format
* tar - old BSD 4.3 tar format
* binary cpio - old cpio with binary header format
* sysVR4 cpio - with and without CRC
*
* This version is a superset of IEEE Std 1003.2b-d3
*
* Summary of Extensions to the IEEE Standard:
*
* 1 READ ENHANCEMENTS
* 1.1 Operations which read archives will continue to operate even when
* processing archives which may be damaged, truncated, or fail to meet
* format specs in several different ways. Damaged sections of archives
* are detected and avoided if possible. Attempts will be made to resync
* archive read operations even with badly damaged media.
* 1.2 Blocksize requirements are not strictly enforced on archive read.
* Tapes which have variable sized records can be read without errors.
* 1.3 The user can specify via the non-standard option flag -E if error
* resync operation should stop on a media error, try a specified number
* of times to correct, or try to correct forever.
* 1.4 Sparse files (lseek holes) stored on the archive (but stored with blocks
* of all zeros will be restored with holes appropriate for the target
* filesystem
* 1.5 The user is notified whenever something is found during archive
* read operations which violates spec (but the read will continue).
* 1.6 Multiple archive volumes can be read and may span over different
* archive devices
* 1.7 Rigidly restores all file attributes exactly as they are stored on the
* archive.
* 1.8 Modification change time ranges can be specified via multiple -T
* options. These allow a user to select files whose modification time
* lies within a specific time range.
* 1.9 Files can be selected based on owner (user name or uid) via one or more
* -U options.
* 1.10 Files can be selected based on group (group name or gid) via one o
* more -G options.
* 1.11 File modification time can be checked against existing file after
* name modification (-Z)
*
* 2 WRITE ENHANCEMENTS
* 2.1 Write operation will stop instead of allowing a user to create a flawed
* flawed archive (due to any problem).
* 2.2 Archives written by pax are forced to strictly conform to both the
* archive and pax the specific format specifications.
* 2.3 Blocking size and format is rigidly enforced on writes.
* 2.4 Formats which may exhibit header overflow problems (they have fields
* too small for large file systems, such as inode number storage), use
* routines designed to repair this problem. These techniques still
* conform to both pax and format specifications, but no longer truncate
* these fields. This removes any restrictions on using these archive
* formats on large file systems.
* 2.5 Multiple archive volumes can be written and may span over different
* archive devices
* 2.6 A archive volume record limit allows the user to specify the number
* of bytes stored on an archive volume. When reached the user is
* prompted for the next archive volume. This is specified with the
* non-standard -B flag. The limit is rounded up to the next blocksize.
* 2.7 All archive padding during write use zero filled sections. This makes
* it much easier to pull data out of flawed archive during read
* operations.
* 2.8 Access time reset with the -t applies to all file nodes (including
* directories).
* 2.9 Symbolic links can be followed with -L (optional in the spec).
* 2.10 Modification or inode change time ranges can be specified via
* multiple -T options. These allow a user to select files whose
* modification or inode change time lies within a specific time range.
* 2.11 Files can be selected based on owner (user name or uid) via one or more
* -U options.
* 2.12 Files can be selected based on group (group name or gid) via one o
* more -G options.
* 2.13 Symlinks which appear on the command line can be followed (without
* following other symlinks; -H flag)
*
* 3 COPY ENHANCEMENTS
* 3.1 Sparse files (lseek holes) can be copied without expanding the holes
* into zero filled blocks. The file copy is created with holes which are
* appropriate for the target filesystem
* 3.2 Access time as well as modification time on copied file trees can be
* preserved with the appropriate -p options.
* 3.3 Access time reset with the -t applies to all file nodes (including
* directories).
* 3.4 Symbolic links can be followed with -L (optional in the spec).
* 3.5 Modification or inode change time ranges can be specified via
* multiple -T options. These allow a user to select files whose
* modification or inode change time lies within a specific time range.
* 3.6 Files can be selected based on owner (user name or uid) via one or more
* -U options.
* 3.7 Files can be selected based on group (group name or gid) via one o
* more -G options.
* 3.8 Symlinks which appear on the command line can be followed (without
* following other symlinks; -H flag)
* 3.9 File inode change time can be checked against existing file before
* name modification (-D)
* 3.10 File inode change time can be checked against existing file after
* name modification (-Y)
* 3.11 File modification time can be checked against existing file after
* name modification (-Z)
*
* 4 GENERAL ENHANCEMENTS
* 4.1 Internal structure is designed to isolate format dependent and
* independent functions. Formats are selected via a format driver table.
* This encourages the addition of new archive formats by only having to
* write those routines which id, read and write the archive header.

* only a single DLIST that has a truncation id of 0 (no inode bits were
* stripped for this device so far). When we spot inode truncation we create
* a new mapping based on the set of bits in the inode which were stripped off.
* so if the top four bits of the inode are stripped and they have a pattern of
* 0110...... (where . are those bits not truncated) we would have a mapping
* assigned for all inodes that has the same 0110.... pattern (with this dev
* number of course). This keeps the mapping sparse and should be able to store
* close to the limit of files which can be represented by the optimal
* combination of dev and inode bits, and without creating a fouled up archive.
* Note we also remap truncated devs in the same way (an exercise for the

.Sh NAME
.Nm tar
.Nd tape archiver
.Sh SYNOPSIS
.Nm tar
.Sm off
.Oo \&- Oc {crtux} Op Fl 014578befHhJjklmOoPpqSvwXZz
.Sm on
.Op Ar archive
.Op Ar blocksize
.\" XXX how to do this right?
.Op Fl C Ar directory
.Op Fl s Ar replstr
.Op Fl T Ar file
.Op Ar file ...
.Sh DESCRIPTION
The
.Nm
command creates, adds files to, or extracts files from an
archive file in
.Dq tar
format.
A tar 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 Ar
.It Fl c , Fl Fl create
Create new archive, or overwrite an existing archive,
adding the specified files to it.
.It Fl r , Fl Fl append
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 , Fl Fl list
List contents of archive.
If any files are named on the
command line, only those files will be listed.
.It Fl u , Fl Fl update
Alias for
.Fl r .
.It Fl x , Fl Fl extract , Fl Fl get
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 Ar
.It Fl b Ar "blocking factor" , Fl Fl block-size Ar "blocking factor"
Set blocking factor to use for the archive.
.Nm
uses 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 , Fl Fl file Ar archive
Filename where the archive is stored.
Defaults to
.Pa /dev/rst0 .
If the archive is of the form:
.Ar [[user@]host:]file
then the archive will be processed using
.Xr rmt 8 .
.It Fl h , Fl Fl dereference
Follow symbolic links as if they were normal files
or directories.
.It Fl J, Fl Fl xz
Compress/decompress archive using
.Xr xz 1 .
.It Fl j, Fl Fl bzip2, Fl Fl bunzip2
Use
.Xr bzip2 1
for compression of the archive.
This option is a GNU extension.
.It Fl k , Fl Fl keep-old-files
Keep existing files; don't overwrite them from archive.
.It Fl l , Fl Fl one-file-system
Do not descend across mount points.
.\" should be '-X'
.It Fl m , Fl Fl modification-time
Do not preserve modification time.
.It Fl O
When creating and appending to an archive, write old-style (non-POSIX) archives.
When extracting from an archive, extract to standard output.
.It Fl o , Fl Fl portability , Fl Fl old-archive
Don't write directory information that the older (V7) style
.Nm
is unable to decode.
This implies the
.Fl O
flag.
.It Fl p , Fl Fl preserve-permissions , Fl Fl preserve
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 , Fl Fl fast-read
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 , Fl Fl sparse
This flag has no effect as
.Nm
always generates sparse files.
.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/[gps]
As in
.Xr ed 1 ,
.Cm old
is a basic regular expression and
.Cm new
can contain an ampersand (\*[Am]), \en (where n is a digit) back-references,
or subexpression matching.
The
.Cm old
string may also contain
.Aq Dv newline
characters.
Any non-null character can be used as a delimiter (/ 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
.Dv standard error
in the following format:
.Dl \*[Lt]original pathname\*[Gt] \*[Gt]\*[Gt] \*[Lt]new pathname\*[Gt]
File or archive member names that substitute to the empty string
are not selected and will be skipped.
The substitutions are applied by default to the destination hard and symbolic
links.
The optional trailing
.Cm s
prevents the substitutions from being performed on symbolic link destinations.
.It Fl v
Verbose operation mode.
.It Fl w , Fl Fl interactive , Fl Fl confirmation
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 z , Fl Fl gzip , Fl Fl gunzip
Compress/decompress archive using
.Xr gzip 1 .
.It Fl B , Fl Fl read-full-blocks
Reassemble small reads into full blocks (For reading from 4.2BSD pipes).
.It Fl C Ar directory , Fl Fl directory 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.
This argument and its parameter may also appear in a file list specified by
.Fl T .
.It Fl H
Only follow symlinks given on command line.
.Pp
Note SysVr3/i386 picked up ISC/SCO UNIX compatibility which implemented
.Dq Fl F Ar file
which was defined as obtaining a list of command line switches and files
on which to operate from the specified file,
but SunOS-5 uses
.Dq Fl I Ar file
because they use
.Sq Fl F
to mean something else.
We might someday provide SunOS-5 compatibility
but it makes little sense to confuse things with ISC/SCO compatibility.
.\".It Fl L
.\"Do not follow any symlinks (do the opposite of
.\".Fl h ).
.It Fl P , Fl Fl absolute-paths
Do not strip leading slashes
.Pq Sq /
from pathnames.
The default is to strip leading slashes.
.It Fl T Ar file , Fl Fl files-from Ar file
Read the names of files to archive or extract from the given file, one
per line.
A line may also specify the positional argument
.Dq Fl C Ar directory .
.It Fl X Ar file , Fl Fl exclude-from Ar file
Exclude files matching the shell glob patterns listed in the given file.
.\" exclude should be '-E' and '-X' should be one-file-system
.Pp
Note that it would be more standard to use this option to mean ``do not
cross filesystem mount points.''
.It Fl Z , Fl Fl compress , Fl Fl uncompress
Compress archive using compress.
.It Fl Fl strict
Do not enable GNU tar extensions such as long filenames and long link names.
.It Fl Fl atime-preserve
Preserve file access times.
.It Fl Fl chroot
.Fn chroot
to the current directory before extracting files.
Use with
.Fl x
and
.Fl h
to make absolute symlinks relative to the current directory.
.It Fl Fl unlink
Ignored, only accepted for compatibility with other
.Nm
implementations.
.Nm
always unlinks files before creating them.
.It Fl Fl use-compress-program Ar program
Use the named program as the program to decompress the input.
.It Fl Fl force-local
Do not interpret filenames that contain a
.Sq \&:
as remote files.
.It Fl Fl insecure
Normally
.Nm
ignores filenames that contain
.Dq ..
as a path component.
With this option, files that contain
.Dq ..
can be processed.
.It Fl Fl no-recursion
Cause files of type directory being copied or archived, or archive members of
type directory being extracted, to match only the directory file or archive
member and not the file hierarchy rooted at the directory.
.El
.Pp
The options
.Op Fl 014578
can be used to select one of the compiled-in backup devices,
.Pa /dev/rstN .
.Sh FILES
.Bl -tag -width "/dev/rst0"
.It Pa /dev/rst0
default archive name
.El
.Sh DIAGNOSTICS
.Nm
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.

.Dt PWD 1
.Os
.Sh NAME
.Nm pwd
.Nd return working directory name
.Sh SYNOPSIS
.Nm
.Op Fl LP
.Sh DESCRIPTION
.Nm
writes the absolute pathname of the current working directory to
the standard output.
.Pp
The following options are available:
.Bl -tag -width indent
.It Fl L
If the
.Ev PWD
environment variable is an absolute pathname that contains
neither "/./" nor "/../" and references the current directory, then
.Ev PWD
is assumed to be the name of the current directory.
.It Fl P
Print the physical path to the current working directory, with symbolic
links in the path resolved.
.El
.Pp
The default for the
.Nm
command is
.Fl P .
.Pp
.Nm
is usually provided as a shell builtin (which may have a different
default).
.Sh EXIT STATUS
The
.Nm
utility exits 0 on success, and \*[Gt]0 if an error occurs.
.Sh SEE ALSO
.Xr cd 1 ,
.Xr csh 1 ,
.Xr ksh 1 ,
.Xr sh 1 ,
.Xr getcwd 3
.Sh STANDARDS
The
.Nm
utility is expected to be conforming to
.St -p1003.1 ,
except that the default is
.Fl P
not
.Fl L .
.Sh HISTORY
A
.Nm
utility appeared in
.At v5 .
.Sh BUGS
In
.Xr csh 1
the command
.Ic dirs
is always faster (although it can give a different answer in the rare case
that the current directory or a containing directory was moved after
the shell descended into it).
.Pp
.Nm
.Fl L
relies on the file system having unique inode numbers.
If this is not true (e.g., on FAT file systems) then
.Nm
.Fl L
may fail to detect that
.Ev PWD
is incorrect.
