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

Tag	Description
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

FUNCTION LETTERS

Tag	Description
One of the following options must be used: -A, --catenate, --concatenate
	append tar files to an archive
-c, --create
	create a new archive
-d, --diff, --compare
	find differences between archive and file system
-r, --append
	append files to the end of an archive
-t, --list
	list the contents of an archive
-u, --update
	only append files that are newer than the existing in archive
-x, --extract, --get
	extract files from an archive
--delete
	delete from the archive (not for use on mag tapes!)

COMMON OPTIONS

Tag	Description
-C, --directory DIR
	change to directory DIR
-f, --file [HOSTNAME:]F
	use archive file or device F (default "-", meaning stdin/stdout)
-j, --bzip2
	filter archive through bzip2, use to decompress .bz2 files
-p, --preserve-permissions

do not attempt to restore ownership when extracting; -o exhibits this behavior when extracting an archive

-O, --to-stdout

extract files to standard output

--occurrence[=NUMBER]

process only the NUMBERth occurrence of each file in the archive; this option is valid only in conjunction with one of the subcommands --delete, --diff, --extract or --list and when a list of files is given either on the command line or via the -T option; NUMBER defaults to 1

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.
