[SOLVED] Bash Check if a Script Ran Successfully (Exit Code not Working)

Issue

I have the following bash script:

echo one
echo two
cd x
echo three

which fails at the 3rd line as there is no directory named x. However, after running the script, when I do $?, 0 is returned, even though the script has an error. How do I detect whether the script ran successfully or not?

Solution

Check the condition of directory existence in the script statements:

[ -d x ] && cd x || { echo "no such directory"; exit 1; }

Or put set -e after shebang line:

#!/bin/bash
set -e
echo one
echo two
cd x
echo three
