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 -xvf foo.tar
              verbosely extract foo.tar

       tar -xzf foo.tar.gz
              extract gzipped foo.tar.gz

       tar -cjf foo.tar.bz2 bar/
              create  bzipped  tar  archive  of  the  directory   bar   called
              foo.tar.bz2

       tar -xjf foo.tar.bz2 -C bar/
              extract bzipped foo.tar.bz2 after changing directory to bar

       tar -xzf foo.tar.gz blah.txt
              extract the file blah.txt from foo.tar.bz2

BUGS

       The  GNU  folks, in general, abhor man pages, and create info documents
       instead.  The maintainer of tar falls into this  category.   Thus  this
       man  page may not be complete, nor current, and was included in the Red
       Hat CVS tree because man is a great tool :).  This man page  was  first
       taken from Debian Linux and has since been loving updated here.
