NAME
tar - manual page for tar 1.23
SYNOPSIS
tar [OPTION...] [FILE]...
DESCRIPTION
GNU ‘tar’ saves many files together into a single tape or disk archive, and can restore individual files from the archive.
Note that this manual page contains just very brief description (or more like a list of possible functionality) originally generated by the help2man utility. The full documentation for tar is maintained
as a Texinfo manual. If the info and tar programs are properly installed at your site, the command ‘info tar’ should give you access to the complete manual.
EXAMPLES
tar -cf archive.tar foo bar
# Create archive.tar from files foo and bar.
tar -tvf archive.tar
# List all files in archive.tar verbosely.
tar -xf archive.tar
# Extract all files from archive.tar.
Main operation mode:
-A, --catenate, --concatenate

-c, --create

-d, --diff, --compare

--delete
delete from the archive (not on mag tapes!)
-r, --append

-t, --list

--test-label
