What is the etymology behind "-j" indicating bzip2 for tar?

  • 3
    There probably isn't a specific reason for why -j was used. -b and -B were already taken, so all obvious choices were impossible. Maybe it's because bzip2's developer is Julian Seward...

    @Paul Do you know of any stackexchange sites that would be appropriate for this question?

  • @MaxNanasy: In any case, this is a question that only the people involved in the decision can answer con authority. You could try the GNU tar mailing list.

  • Sorry @MaxNanasy I don't. The switch was introduced in 2000 by Paul Eggert. Perhaps he is still around to ask? cvs.savannah.gnu.org/viewvc/tar/tar/…
