If you have that in a variable, which you presumably would if you're reading them one at a time, you can use "remove longest matching prefix" substitution.

    $ i="/podcast/with/nasty'--c h a r$/and/stuff/track1.mp3"
    $ echo "${i##*/}"
    track1.mp3

This part is really cryptic, I would prefer

    $ function remove_longest_matching_prefix () { echo "${1##$2}"; }
    $ remove_longest_matching_prefix "$i" '*/'
    track1.mp3

awk -F/ accepts stream as in perl example

You still get +1 for providing a pointer to the explanation while remaining clear and succinct.
