Shell Scripting / Bash Tricks

Stop your shell scripts from dying on partial commands

🧩 The Challenge

You write a script expecting a chain of commands to work, but the whole thing goes sideways because one pipe in the middle failed silently. I’ve spent way too many nights debugging why a backup script finished with a success message when half the data never actually moved.

💡 The Fix

Flip the pipefail option on at the top of your script so that bash actually pays attention to the exit status of every command in a pipeline, not just the last one.

set -o pipefail

⚙️ Why It Works

Bash defaults to only caring about the exit code of the final command in a pipe, which is usually just the exit status of the last process. Enabling this forces the shell to return the status of the first failing command in that chain, preventing those annoying silent failures.

🚀 Pro-Tip: Use this in combination with set -e to make your scripts exit immediately when anything breaks.
