Put set -e in bash scripts to exit on error.
#!/bin/bash
cd directory
echo "Deleting everything in the current directory"
$ ./script.sh
./script.sh: line 3: cd: stuff: No such file or directory
Deleting everything in the current directory
$
Oh no!
You can use set -e near the top of your script, or simply append -e to the shebang:
#!/bin/bash -e
cd directory
echo "Deleting everything in the current directory"
$ ./script.sh
./script.sh: line 5: cd: stuff: No such file or directory
Much better.
