Bash – how to stop at error

By on

To stop a bash script at first error use set -e. To undo it use set +e.

#!/bin/bash
set +e
ls -l /opt/non_existing_dir1
set -e
echo "I will be printed"
ls -l /opt/non_existing_dir2
echo "I will not be printed"
I will be printed
ls: cannot access /opt/non_existing_dir1: No such file or directory
ls: cannot access /opt/non_existing_dir2: No such file or directory
Env: GNU bash, version 4.2.46
