It all depends. The first example posted showed more code (for testing UID
range) plus it indicated that the script will be doing other work too.
It is often easier and cleaner to use "if" statements than trying to place
a bunch of code within parenthesis for example.
|| (echo "Sorry." ; and what about the rest ; should this exit here; jump \
to there ; etc. )
So instead of faultfinding, maybe consider something like "Here's an
another idea ..."
