#!/bin/bash
set -e
function foo() {
# commands that might fails and I want to exit my script
...
echo "result I need as output"
}
my_var=$(foo)
echo "I don't want this if there is an error inside foo"Using set -e (in bash 4.4.19) does not seem to work with subshells i.e. the last echocommand is still being executed). How can I write the code to make the script exit if any of the commands inside foo terminate with non-zero exit code.
