but you can't do that. First you have to decompress, then edit, then compress again. In order
to see the contents of a tarball all you have to do is use the "t" flag, for example
tar -jtf tarball.bz2

You can do system backups as well if you add the "P" flag to the options not to stip
leading "/".

The only other compression scheme that I know is 'zip' which can be combined with 'tar'
by passing the 'z' flag instead of 'j' for bz2. Zip works well and fast for relatively small tarballs.

Notice that if you choose any sort of compression for a tarball then you cannot do any
incremental additions to it.
