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

TagDescription
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.gz

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.

REPORTING BUGS

Please report bugs via https://bugzilla.redhat.com

SEE ALSO

tar is maintained as a Texinfo manual. If the info and tar programs are properly installed at your site, the command
TagDescription
info tar
should give you access to the complete manual.
