Is there a way to write a bash function which aborts the whole execution, no matter how it is called?

Question

I was using \"exit 1\" statement in my bash functions to terminate the whole script and it worked fine:

function func()
{
   echo \"Goodbye\"
   exit 1
}
ech         


        

Answer 1

You can use set -e which exits if a command exits with a non-zero status:

set -e 
func
set +e

Or grab the return value:

(func) || exit $?
