Hi folks, I create a tarred file then compressed with bzip with following command line; # tar -jcpf AAA.bz2 /home/path/to/dirA dirA is about 2G in size. After working several days on dirA I want to create a new compressed tarred file. Instead of repeating the above command, is there a way starting from the old file AAA.bz2 making use of the options -u, -N, -G, etc. to reduce the compressing time? I looked around on man tar and Internet and could not sort out their combination on the command line. Could you please shed me some light. TIA B.R. SL
