I would always go for the shell solution. I'll have deleted all the files even before you've finished typing your Perl program.

Well, since you are being snarky I'll respond in kind: I doubt it, i reckon youll still be fighting with the shell syntax, and doublechecking that the switches and utilities you got so used to in bash are actually present in the shell you need to run it on. And even then you still wont be 100% confident that it will all work as expected.

Which to me is the reason that perl scripts beat shell scripts hands down pretty well every time. I can use the same perl script on every shell and OS I can find pretty much. Your shell script will only work on a small subset of them, and will require massive changes for some of them.

Shell scripts are only worth thinking about if you are a monoculture programmer. Since I'm not I view them mostly with contempt. Who needs shell scripts when you have perl scripts instead?
