DESCRIPTION
     The tar command archives and extracts files to  and  from  a
     single  file  called  a tarfile. A tarfile is usually a mag-
     netic tape, but it can be any file. tar's actions  are  con-
     trolled by the key argument.  The key is a string of charac-
     ters containing exactly one function letter (c, r, t , u, or
     x)  and zero or more function modifiers (letters or digits),
     depending on the function letter used. The key  string  con-
     tains  no  SPACE characters. Function modifier arguments are
     listed on the command  line  in  the  same  order  as  their
     corresponding function modifiers appear in the key string.

     The -I include-file, -C directory file, and  file  arguments
     specify  which  files  or  directories are to be archived or
     extracted. In all cases,  appearance  of  a  directory  name
     refers to the files and (recursively) subdirectories of that
     directory. Arguments appearing within braces ({ })  indicate
     that one of the arguments must be specified.

OPERANDS
     The following operands are supported:

     -C directory file       Performs a chdir (see cd(1))  opera-
                             tion on directory and performs the c
                             (create) or r (replace) operation on
                             file.  Use short relative path names
                             for file. If file  is  ".",  archive
                             all files in directory. This operand
                             enables archiving files from  multi-
                             ple  directories  not  related  by a
                             close common parent.


     -I include-file         Opens include-file containing a list
                             of  files,  one per line, and treats
                             it  as   if   each   file   appeared
                             separately  on  the command line. Be
                             careful of  trailing  white  spaces.
                             Also beware of leading white spaces,
                             since, for each line in the included
                             file,  the  entire  line (apart from
                             the newline) will be used  to  match
                             against  the initial string of files
                             to  include.  In  the   case   where
                             excluded   files   (see  X  function
                             modifier) are also  specified,  they
                             take  precedence  over  all included
                             files. If a  file  is  specified  in
                             both   the   exclude-file   and  the
                             include-file  (or  on  the   command
                             line), it will be excluded.


     file                    A path name of  a  regular  file  or
                             directory  to  be archived (when the
                             c, r or u functions are  specified),
                             extracted  (x)  or  listed (t). When
                             file is the path name  of  a  direc-
                             tory,  the  action applies to all of
                             the  files  and  (recursively)  sub-
                             directories of that directory.

                             When a file is archived, and  the  E
                             flag (see Function Modifiers) is not
                             specified,   the   filename   cannot
                             exceed  256 characters. In addition,
                             it must be  possible  to  split  the
                             name  between parent directory names
                             so that the prefix is no longer than
                             155  characters  and  the name is no
                             longer than 100 characters. If E  is
                             specified,  a name of up to PATH_MAX
                             characters may be specified.

                             For example, a file  whose  basename
                             is  longer than 100 characters could
                             not be archived without using the  E
                             flag. A file whose directory portion
                             is 200 characters and whose basename
                             is  50  characters could be archived
                             (without using E) if a slash appears
                             in  the  directory name somewhere in
                             character positions 151-156.


  Function Letters
     The function portion of the key is specified by one  of  the
     following letters:

     c    Create. Writing begins at the beginning of the tarfile,
          instead of at the end.


     r    Replace. The named files are written at the end of  the
          tarfile.  A  file created with extended headers must be
          updated with extended headers (see E flag  under  Func-
          tion   Modifiers).  A  file  created  without  extended
          headers cannot be modified with extended headers.


     t    Table of Contents. The names of the specified files are
          listed each time they occur in the tarfile.  If no file
          argument is given, the names of all files and any asso-
          ciated  extended  attributes in the tarfile are listed.
          With the v function  modifier,  additional  information
          for the specified files is displayed.


     u    Update. The named files are written at the end  of  the
          tarfile  if  they are not already in the tarfile, or if
          they have been modified since last written to that tar-
          file.  An  update can be rather slow. A tarfile created
          on a 5.x system cannot be updated on a  4.x  system.  A
          file created with extended headers must be updated with
          extended headers (see E flag under Function Modifiers).
          A file created without extended headers cannot be modi-
          fied with extended headers.


     x    Extract or restore. The named files are extracted  from
          the  tarfile  and written to the directory specified in
          the tarfile, relative to the current directory. Use the
          relative  path  names  of  files  and directories to be
          extracted.

          Absolute path names contained in the  tar  archive  are
          unpacked  using  the  absolute path names, that is, the
          leading forward slash (/) is not stripped off.

          If a named file matches a directory whose contents  has
          been  written  to the tarfile, this directory is recur-
          sively extracted. The  owner,  modification  time,  and
          mode  are restored (if possible); otherwise, to restore
          owner, you must be  the  super-user.  Character-special
          and  block-special  devices  (created by mknod(1M)) can
          only be extracted by the super-user. If no  file  argu-
          ment  is  given,  the  entire content of the tarfile is
          extracted. If the tarfile contains several  files  with
          the  same name, each file is written to the appropriate
          directory, overwriting the previous one. Filename  sub-
          stitution wildcards cannot be used for extracting files
          from the archive. Rather, use a command of the form:

            tar xvf ... /dev/rmt/0 `tar tf ... /dev/rmt/0 | \
                grep 'pattern' `




     When extracting tapes created with the  r  or  u  functions,
     directory modification times may not be set correctly. These
     same functions cannot be used with many tape drives  due  to
     tape  drive  limitations such as the absence of backspace or
     append capabilities.

     When using the r, u, or x functions or the X function modif-
     ier,  the  named  files must match exactly the corresponding
     files in the tarfile. For example,  to  extract  ./thisfile,
     you  must  specify ./thisfile, and not thisfile. The t func-
     tion displays how each file was archived.

  Function Modifiers
     The characters below may be used  in  conjunction  with  the
     letter that selects the desired function.

     b blocksize    Blocking Factor. Use when reading or  writing
                    to  raw  magnetic archives (see f below). The
                    blocksize argument specifies  the  number  of
                    512-byte  tape  blocks to be included in each
                    read or write operation performed on the tar-
                    file.  The  minimum  is 1, the default is 20.
                    The maximum value is a function of the amount
                    of memory available and the blocking require-
                    ments of the specific  tape  device  involved
                    (see  mtio(7I) for details.) The maximum can-
                    not exceed INT_MAX/512 (4194303).

                    When a tape archive is being read, its actual
                    blocking   factor   will   be   automatically
                    detected, provided that it is  less  than  or
                    equal  to  the  nominal  blocking factor (the
                    value  of  the  blocksize  argument,  or  the
                    default value if the b modifier is not speci-
                    fied).  If  the  actual  blocking  factor  is
                    greater  than  the nominal blocking factor, a
                    read error will  result.  See  Example  5  in
                    EXAMPLES.


     B              Block. Force tar to  perform  multiple  reads
                    (if  necessary)  to read exactly enough bytes
                    to  fill  a  block.  This  function  modifier
                    enables  tar  to  work  across  the Ethernet,
                    since pipes and sockets return partial blocks
                    even  when more data is coming.  When reading
                    from  standard  input,  "-",  this   function
                    modifier  is  selected  by  default to ensure
                    that tar can recover from short reads.


     D              Data change warnings. Used with c,  r,  or  u
                    function  letters.  Ignored with t or x func-
                    tion letters. If the size of a  file  changes
                    while  the file is being archived, treat this
                    condition as  a  warning  instead  of  as  an
                    error.  A warning message will still be writ-
                    ten, but the exit status is not affected.


     e              Error. Exit immediately with a positive  exit
                    status  if  any  unexpected errors occur. The
                    SYSV3  environment  variable  overrides   the
                    default  behavior. (See ENVIRONMENT VARIABLES
                    section below.)


     E              Write a tarfile with extended headers.  (Used
                    with  c,  r,  or  u function letters. Ignored
                    with t or x function letters.) When a tarfile
                    is written with extended headers, the modifi-
                    cation time is maintained with a  granularity
                    of microseconds rather than seconds. In addi-
                    tion, filenames no longer than PATH_MAX char-
                    acters  that could not be archived without E,
                    and file sizes greater  than  8GB,  are  sup-
                    ported.  The  E flag is required whenever the
                    larger files and/or files with longer  names,
                    or  whose  UID/GID  exceed 2097151, are to be
                    archived,   or   if   time   granularity   of
                    microseconds is desired.


     f              File. Use the tarfile argument as the name of
                    the    tarfile.    If    f    is   specified,
                    /etc/default/tar is not  searched.  If  f  is
                    omitted, tar will use the device indicated by
                    the TAPE environment variable, if set. Other-
                    wise, tar will use the default values defined
                    in /etc/default/tar. The number matching  the
                    archiveN  string is used as the output device
                    with the  blocking  and  size  specifications
                    from the file. For example,

                      tar -c 2/tmp/*


                    writes the output to the device specified  as
                    archive2 in /etc/default/tar.

                    If the name of the tarfile is "-", tar writes
                    to  the  standard  output  or  reads from the
                    standard input, whichever is appropriate. tar
                    can  be  used  as the head or tail of a pipe-
                    line. tar can also be used  to  move  hierar-
                    chies with the command:

                      example% cd fromdir; tar cf - .| (cd todir; tar xfBp -)




     F              With one F argument, tar excludes all  direc-
                    tories  named  SCCS and RCS from the tarfile.
                    With two  arguments,  FF,  tar  excludes  all
                    directories  named  SCCS  and  RCS, all files
                    with .o as their suffix, and all files  named
                    errs,  core, and a.out. The SYSV3 environment
                    variable overrides the default behavior. (See
                    ENVIRONMENT VARIABLES section below.)


     h              Follow symbolic links as if they were  normal
                    files  or directories. Normally, tar does not
                    follow symbolic links.


     i              Ignore directory checksum errors.


     k size         Requires tar to use the size argument as  the
                    size of an archive in kilobytes. This is use-
                    ful when the archive is intended for a  fixed
                    size device such as floppy disks. Large files
                    are then split across volumes if they do  not
                    fit in the specified size.

     l              Link.  Output  error  message  if  unable  to
                    resolve   all   links   to  the  files  being
                    archived. If l is  not  specified,  no  error
                    messages are printed.


     m              Modify. The modification time of the file  is
                    the  time of extraction. This function modif-
                    ier is valid only with the x function.


     n              The file being read  is  a  non-tape  device.
                    Reading  of  the  archive is faster since tar
                    can randomly seek around the archive.


     o              Ownership. Assign to extracted files the user
                    and group identifiers of the user running the
                    program, rather than those on  tarfile.  This
                    is  the default behavior for users other than
                    root. If the o function modifier is  not  set
                    and  the  user  is  root, the extracted files
                    will take on the group and  user  identifiers
                    of  the  files  on  tarfile (see chown(1) for
                    more information). The o function modifier is
                    only valid with the x function.


     p              Restore the named  files  to  their  original
                    modes,  and  ACLs if applicable, ignoring the
                    present  umask(1).  This   is   the   default
                    behavior  if invoked as super-user with the x
                    function  letter  specified.  If  super-user,
                    SETUID,   and  sticky  information  are  also
                    extracted, and files are restored with  their
                    original  owners and permissions, rather than
                    owned by root. When this function modifier is
                    used with the c function, ACLs are created in
                    the tarfile  along  with  other  information.
                    Errors will occur when a tarfile with ACLs is
                    extracted by previous versions of tar.


     P              Suppress the addition of a  trailing  "/"  on
                    directory entries in the archive.


     q              Stop after extracting the first occurrence of
                    the  named  file.  tar will normally continue
                    reading  the   archive   after   finding   an
                    occurrence of a file.

     T              This modifier is only available if the system
                    is configured with Trusted Extensions.

                    When this modifier is used with the  function
                    letter  c, r, or u for creating, replacing or
                    updating a  tarfile,  the  sensitivity  label
                    associated with each archived file and direc-
                    tory is stored in the tarfile.

                    Specifying T implies the function modifier p.

                    When used with  the  function  letter  x  for
                    extracting  a  tarfile, the tar program veri-
                    fies that the file's sensitivity label speci-
                    fied  in  the  archive equals the sensitivity
                    label of the destination directory.  If  not,
                    the file is not restored. This operation must
                    be invoked  from  the  global  zone.  If  the
                    archived  file has a relative pathname, it is
                    restored to the corresponding directory  with
                    the same label, if available. This is done by
                    prepending to the current destination  direc-
                    tory  the  root  pathname  of  the zone whose
                    label  equals  the  file.  If  no  such  zone
                    exists, the file is not restored.

                    Limited support is  provided  for  extracting
                    labeled archives from Trusted Solaris 8. Only
                    sensitivity labels, and multi-level directory
                    specifications   are  interpreted.  Privilege
                    specifications and audit attribute flags  are
                    silently    ignored.   Multilevel   directory
                    specifications including  symbolic  links  to
                    single  level directories are are mapped into
                    zone-relative pathnames if a  zone  with  the
                    same  label  is  available.  This  support is
                    intended  to  facilitate  migration  of  home
                    directories.  Architectural  differences pre-
                    clude the extraction of  arbitrarily  labeled
                    files  from Trusted Solaris 8 into  identical
                    pathnames in Trusted Extensions. Files cannot
                    be  extracted  unless  their  archived  label
                    matches the destination label.


     v              Verbose. Output the name of  each  file  pre-
                    ceded  by  the  function  letter.  With the t
                    function, v provides  additional  information
                    about  the  tarfile  entries.  The listing is
                    similar to the  format  produced  by  the  -l
                    option of the ls(1) command.

     w              What. Output the action to be taken  and  the
                    name  of the file, then await the user's con-
                    firmation. If the  response  is  affirmative,
                    the   action  is  performed;  otherwise,  the
                    action is not performed. This function modif-
                    ier cannot be used with the t function.


     X              Exclude. Use the exclude-file argument  as  a
                    file containing a list of relative path names
                    for files (or  directories)  to  be  excluded
                    from  the tarfile when using the functions c,
                    x, or t. Be careful of trailing white spaces.
                    Also  beware  of leading white spaces, since,
                    for each  line  in  the  excluded  file,  the
                    entire  line (apart from the newline) will be
                    used to match against the initial  string  of
                    files  to  exclude. Lines in the exclude file
                    are matched exactly, so an entry like  "/var"
                    will not exclude the /var directory if tar is
                    backing  up  relative  pathnames.  The  entry
                    should   read   "./var"   under   these  cir-
                    cumstances. The tar command does  not  expand
                    shell  metacharacters in the exclude file, so
                    specifying entries like "*.o" will  not  have
                    the  effect of excluding all files with names
                    suffixed with ".o".  If  a  complex  list  of
                    files  is  to  be  excluded, the exclude file
                    should be generated by some means such as the
                    find(1) command with appropriate conditions.

                    Multiple X arguments may be  used,  with  one
                    exclude-file  per argument. In the case where
                    included files (see -I include-file  operand)
                    are  also  specified, the excluded files take
                    precedence over all included files. If a file
                    is specified in both the exclude-file and the
                    include-file (or on  the  command  line),  it
                    will be excluded.


     @              Include extended attributes  in  archive.  By
                    default,  tar  does not place extended attri-
                    butes in the archive.  With  this  flag,  tar
                    will  look  for  extended  attributes  on the
                    files to be placed in  the  archive  and  add
                    them  to  the archive. Extended attributes go
                    in the archive as special files with  a  spe-
                    cial  type  label. When this modifier is used
                    with the x function, extended attributes  are
                    extracted from the tape along with the normal
                    file data. Extended attribute files can  only
                    be  extracted  from  an  archive as part of a
                    normal file extract. Attempts  to  explicitly
                    extract attribute records are ignored.


     [0-7]          Select an alternative drive on which the tape
                    is mounted. The default entries are specified
                    in /etc/default/tar. If no digit or  f  func-
                    tion  modifier  is  specified,  the  entry in
                    /etc/default/tar  with  digit  "0"   is   the
                    default.


USAGE
     See largefile(5) for the description of the behavior of  tar
     when  encountering  files greater than or equal to 2 Gbyte (
     2^31 bytes).

     The automatic determination of the  actual  blocking  factor
     may  be fooled when reading from a pipe or a socket (see the
     B function modifier below).

     1/4" streaming tape has an inherent blocking factor  of  one
     512-byte block. It can be read or written using any blocking
     factor.

     This function modifier works for archives on disk files  and
     block special devices, among others, but is intended princi-
     pally for tape devices.

     For information on tar header format, see archives.h(3HEAD).

EXAMPLES
     Example 1 Creating an archive of your home directory

     The following is an example using tar to create  an  archive
     of   your   home  directory  on  a  tape  mounted  on  drive
     /dev/rmt/0:


       example% cd
       example% tar cvf /dev/rmt/0 .
       messages from tar



     The c function letter means create the archive. The v  func-
     tion modifier outputs messages explaining what tar is doing.
     The f function modifier indicates that the tarfile is  being
     specified  (/dev/rmt/0  in this example). The dot (.) at the
     end of the command line indicates the current directory  and
     is the argument of the f function modifier.
     Display the table of contents of the tarfile with  the  fol-
     lowing command:


       example% tar tvf /dev/rmt/0



     The output will be similar to the following  for  the  POSIX
     locale:


       rw-r--r--   1677/40    2123    Nov  7 18:15 1985    ./test.c
       ...
       example%



     The columns have the following meanings:


         o    column 1 is the access permissions to ./test.c

         o    column 2 is the user-id/group-id of ./test.c

         o    column 3 is the size of ./test.c in bytes

         o    column 4 is the modification date of ./test.c. When
              the  LC_TIME  category  is  not  set  to  the POSIX
              locale, a different format and date order field may
              be used.

         o    column 5 is the name of ./test.c

     To extract files from the archive:


       example% tar xvf /dev/rmt/0
       messages from tar
       example%



     If there are multiple archive  files  on  a  tape,  each  is
     separated  from  the following one by an EOF marker. To have
     tar read the first and second archives from a tape with mul-
     tiple  archives on it, the non-rewinding version of the tape
     device name must be used with the f  function  modifier,  as
     follows:


       example% tar xvfp /dev/rmt/0n read first archive from tape
       messages from tar
       example% tar xvfp /dev/rmt/0n read second archive from tape
       messages from tar
       example%



     Notice that in some earlier releases, the above scenario did
     not  work correctly, and intervention with mt(1) between tar
     invocations was necessary. To emulate the old behavior,  use
     the  non-rewind  device name containing the letter b for BSD
     behavior. See the Close Operations section of  the  mtio(7I)
     manual page.


     Example 2 Archiving files from /usr/include and from /etc to
     default tape drive 0

     To archive files from /usr/include and from /etc to  default
     tape drive 0:


       example% tar c -C /usr  include -C /etc .



     The table of contents from the resulting tarfile would  pro-
     duce output like the following:


       include/
       include/a.out.h
       and all the other files in /usr/include ...
       ./chown and all the other files in /etc



     To extract all files in the include directory:


       example% tar xv include
       x include/, 0 bytes, 0 tape blocks \
          and all files under include ...



     Example 3 Transferring files across the network

     The following is an example  using  tar  to  transfer  files
     across the network. First, here is how to archive files from
     the local machine (example) to a tape  on  a  remote  system
     (host):
       example% tar cvfb - 20 files| \
          rsh host dd of=/dev/rmt/0  obs=20b
       messages from tar
       example%



     In the example above, we are creating a tarfile with  the  c
     key  letter,  asking  for verbose output from tar with the v
     function modifier, specifying the name of the output tarfile
     using  the f function modifier (the standard output is where
     the tarfile appears, as indicated  by  the  `-'  sign),  and
     specifying  the blocksize (20) with the b function modifier.
     If you want to change the blocksize,  you  must  change  the
     blocksize  arguments  both  on the tar command and on the dd
     command.


     Example 4 Retrieving files from a tape on the remote  system
     back to the local system

     The following is an example that uses tar to retrieve  files
     from a tape on the remote system back to the local system:


       example% rsh -n host dd if=/dev/rmt/0 bs=20b | \
          tar xvBfb - 20 files
       messages from tar
       example%



     In the example above, we are  extracting  from  the  tarfile
     with  the  x  key letter, asking for verbose output from tar
     with the v function modifier, telling tar it is reading from
     a  pipe with the B function modifier, specifying the name of
     the input tarfile using the f function modifier  (the  stan-
     dard input is where the tarfile appears, as indicated by the
     "-" sign), and specifying the  blocksize  (20)  with  the  b
     function modifier.


     Example 5 Creating an archive of the home directory

     The following example creates an archive of the home  direc-
     tory on /dev/rmt/0 with an actual blocking factor of 19:


       example% tar cvfb /dev/rmt/0 19 $HOME



     To recognize this archive's actual blocking  factor  without
     using the b function modifier:


       example% tar tvf /dev/rmt/0
       tar: blocksize = 19
       ...



     To recognize this archive's actual blocking factor  using  a
     larger nominal blocking factor:


       example% tar tvf /dev/rmt/0 30
       tar: blocksize = 19
       ...



     Attempt to recognize this archive's actual  blocking  factor
     using a nominal blocking factor that is too small:


       example% tar tvf /dev/rmt/0 10
       tar: tape read error



ENVIRONMENT VARIABLES
     SYSV3    This variable  is  used  to  override  the  default
              behavior   of   tar,   provide  compatibility  with
              INTERACTIVE UNIX Systems and SCO UNIX  installation
              scripts, and should not be used in new scripts. (It
              is intended for compatibility purposes only.)  When
              set,  the  following function modifiers behave dif-
              ferently:

              F filename    Uses filename to  obtain  a  list  of
                            command  line  switches  and files on
                            which to operate.


              e             Prevents  files  from   being   split
                            across  volumes. If there is insuffi-
                            cient room on one volume, tar prompts
                            for  a  new  volume. If the file will
                            not fit on the new volume, tar  exits
                            with an error.



     See environ(5) for descriptions of the following environment
     variables  that  affect  the  execution  of  tar:  LC_CTYPE,
     LC_MESSAGES, LC_TIME, TZ, and NLSPATH.

EXIT STATUS
     The following exit values are returned:

     0     Successful completion.

DIAGNOSTICS
     Diagnostic messages are output for bad  key  characters  and
     tape  read/write errors, and for insufficient memory to hold
     the link tables.

NOTES
     There is no way to access the n-th occurrence of a file.

     Tape errors are handled ungracefully.

     When the Volume Management daemon is  running,  accesses  to
     floppy  devices  through  the conventional device names (for
     example, /dev/rdiskette) may not succeed. See  vold(1M)  for
     further details.

     The tar archive format allows UIDs and GIDs up to 2097151 to
     be  stored  in  the archive header. Files with UIDs and GIDs
     greater than this value will be archived with  the  UID  and
     GID of 60001.

     If an archive is created that  contains  files  whose  names
     were  created  by  processes  running in multiple locales, a
     single locale that uses a full 8-bit codeset  (for  example,
     the  en_US locale) should be used both to create the archive
     and to extract files from the archive.

     Neither the r function letter nor the u function letter  can
     be  used  with  quarter-inch archive tapes, since these tape
     drives cannot backspace.

     Since tar has no options, the standard "--" argument that is
     normally used in other utilities to terminate recognition of
     options is not needed. If used, it is recognized only as the
     first argument and is ignored.

     Since -C directory  file  and  -I  include-file  are  multi-
     argument  operands, any of the following methods can be used
     to archive or extract a file named -C or -I:

         1.   Specify them using file  operands  containing  a  /
              character on the command line (such as /home/joe/-C
              or ./-I).

         2.   Include them in an include file  with  -I  include-
              file.

         3.   Specify the directory in which the file resides:

                -C directory -C


              or
