More Bash tricks

While trying to figure out how to pack several scripts of functionality into a single script to make it a bit more portable (and depending on filesystem, possibly more efficient), I came up with the following concept, which has probably been used in quite a few programs before for consolidation purposes.

case "$(basename $0)" in
    "rip.tv.sh")
        [tv-dvd rip procedure]
    ;;
    "rip.movie.sh")
        [movie-dvd procedure]
    ;;
    "rip.trailer.sh")
        [music video or trailer rip procedure]
    ;;
esac

Of course, in order to use this, you then have to symlink (or hard link, your choice) the alternate names to the script to the actual script.
