Why am I not surprised that the PERL part could be solved with bash in the same space. Why are you so eager to use lang on top of lang, in such simple cases?

  Feel free to demonstrate. Take a long path with nasty characters and give me the ending file name. I want "track1.mp3" returned from: /podcast/with/nasty'--c h a r$/and/stuff/track1.mp3
  • AareyBaba 6y ago
    $ basename "/podcast/with/nasty'--c h a r$/and/stuff/track1.mp3" track1.mp3

    $ path="/podcast/with/nasty'--c h a r$/and/stuff/track1.mp3" $ echo "${path##*/}" track1.mp3 $ basename "${path}" track1.mp3 $ echo "${path}" | awk -F/ '{print $NF}' track1.mp3

    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 [Edit: 'thezilch beat me too it by a couple of minutes]

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

      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

    In zsh it would be echo “${uglypath:t}”
