NAME

       tar - The GNU version of the tar archiving utility

SYNOPSIS

       tar  [ - ] A --catenate --concatenate | c --create | d --diff --compare
       | --delete | r --append | t --list | u --update | x --extract  --get  [
       options ] pathname [ pathname ... ]

DESCRIPTION

       This  manual  page  documents  the  GNU  version  of tar , an archiving
       program designed to store and extract files from an archive file  known
       as  a  tarfile.   A tarfile may be made on a tape drive, however, it is
       also common to write a tarfile to a normal file.  The first argument to
       tar  must  be  one  of  the  options: Acdrtux, followed by any optional
       functions.  The final arguments to tar are the names of  the  files  or
       directories  which  should  be  archived.  The  use of a directory name
       always implies that the subdirectories below should be included in  the
       archive.

EXAMPLES

       tar -xvvf foo.tar
              extract foo.tar

       tar -xvvzf foo.tar.gz
              extract gzipped foo.tar.gz

       tar -cvvf foo.tar foo/
              tar contents of folder foo in foo.tar

              WARNING:  some previous versions of tar used option -I to filter
              through bzip2.  When writing scripts, use --bzip2 instead of  -j

ENVIRONMENT

       The  behavior  of  tar  is  controlled  by  the  following  environment
       variables, among others:

       TAPE   Device or  file  to  use  for  the  archive  if  --file  is  not
              specified.   If this environment variable is unset, use stdin or
              stdout instead.

       TAR_OPTIONS
              Options to prepend to  those  specified  on  the  command  line,
              separated  by  whitespace.   Embedded backslashes may be used to
              escape whitespace or backslashes within an option.

BUGS

       The GNU folks, in general, abhor man pages, and create  info  documents
       instead.   Unfortunately,  the info document describing tar is licensed
       under the GFDL with invariant cover texts, which  violates  the  Debian
       Free  Software Guidelines.  As a result, the info documentation for tar
       is not included in the Debian package.

       If you want to read the complete  documentation  for  GNU  tar,  please
       refer to the online version at

                 <http://www.gnu.org/software/tar/manual/index.html>

       This  man  page  was  created for the Debian distribution.  It does not
       describe all of the functionality of tar, and it is often out of  date.
       Patches  to  improve  the coverage and/or accuracy of this man page are
       appreciated, and should be filed as wishlist severity bugs against  the
       Debian tar package, not submitted to the GNU tar maintainers.
