in thread Review of my script
When you type something like:
find-junk | xargs rm -f
... and find-junk bails out with an error message, you don't want the error message piped to rm -f, do you?
So a convention has arisen to provide usage instructions on STDERR if the program has been called incorrectly, but on STDOUT if the program has been called with an explicit --help.
fisher's suggested code does precisely this. It only selects STDERR if $err is a true value.
