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

I guess better is

#!/bin/bash
set -e
trap "exit 1" ERR

myfunc() {
     set -x # OPTIONAL TO SHOW ERROR
     echo "Exit with failure"
     set +x # OPTIONAL
     exit 1
}
echo "BEFORE..."
myvar="$(myfunc)"
echo "AFTER..But not shown"
