Indeed, thank you for mentioning that - I was going to suggest similar.

That said, if you do (ie: scratch files, things outside of control, whatever), consider the directory stack:

Using 'pushd' and 'popd' can save your fingers/brain from getting lost in context.

I like using subshells for this:

  (
      cd dir
      for f in ./*; [..]
  )

There's a few scenarios where this won't work (mainly if you want to set a variable from the "outer scope"), but 99% of the time it works nicely.

Ah, that's a nice/neat thought - thank you for sharing! Makes total sense, temporary/disposable shell for such things
