Long options are --bzip2 or --bunzip2.
Wrong. Gnu tar has no separate option for bzip2, although patches float around (and they use at least three or four different letters, -y, -I etc.) Here's what the maintainer says in the FAQ:
From: François Pinard <pinard@IRO.UMontreal.CA>
. + Q: Why isn't there some `--bzip2' option to `tar'?
I'm trying to not implement new options to `tar', when the functionality is easily obtainable by other means. One may write `--use=bzip2' to get an effect similar to various suggested `--bzip2' options. This is longer to write than a short option letter, but single letter options are a scarce resource, which I treat as such. Not all hope is lost, however. Jean-loup Gailly writes that he is working with the author of `bzip2' to integrate a slightly improved version of `bzip2' inside `zlib.' As `paxutils' will eventually use `zlib', this should give us `bzip2' support rather transparently, right over the `z' option. Also, `z' will become optional on extraction, as `tar' will be made to automatically recognise when an archive is compressed. So, we are going into the proper direction, although progress is admittedly slow.
