====== 2022-06-04 - bash and RAII - continued ======

couple days ago i wrote about [[:blog:2022:05:29:2022-05-29 - bash and RAII|RAII in bash]]. i forgot to mention 1 more thing there. when cleanup procedure is more complicated than simple ''rm -rf foobar'' it's worth to make it a separate function:

<code bash>
# ...
function cleanup
{
  rm -rf "$VAR_TO_SANITIZE"
  rm -fv /path/to/lock
  umount /media/foobar
}
trap cleanup EXIT
# ...
