Question

I have a script test.sh

#/!bin/bash
set -e
trap errorhandler ERR

errorhandler(){
    status=$?
    trap - ERR
    exit $status
}

echo "$@"

exit 0

when I call sh test.sh 'Hey' it will print -e instead of Hey.

My work around is surround set -e with backticks but dont know if it still works as intended

Another workaround is to store it in a variable in the first line but I would like my set -e in the first line for one obvious reason (handling an error).

Is there a clever way to do this? Like “Hey don’t touch my $@” command.

Answer 1

Got it! -e and –e notice the dash. the first one is correct.

Lesson learned. Do not copy code directly from html.
