TAR(1)                           User Commands                          TAR(1)
    
    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

                  delete from the archive (not on mag tapes!)
