tar

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

FUNCTION LETTERS

One of the following options must be used:
-A, --catenate, --concatenate
append tar files to an archive
-c, --create

-d, --diff, --compare

exclude files matching PATTERN
-f, --file [HOSTNAME:]F 
use archive file or device F (default "-", meaning stdin/stdout)
-F, --info-script F, --new-volume-script F
run script at end of each tape (implies -M)

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 It does not describe all of the functionality of tar, and it is often out of date.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.
