XK0-006 Automation, Orchestration, and Scripting Practice Question
A Linux administrator is troubleshooting a Bash script that unexpectedly terminates when a command fails. The script uses `#!/bin/bash`. Which of the following commands, if placed at the beginning of the script, would cause it to exit on any command failure?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
set -e
The `set -e` option makes the shell exit immediately if a command exits with a non-zero status.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
set -u
Why it's wrong here
set -u treats unset variables as an error but does not exit on command failure.
- ✗
trap 'exit 1' ERR
Why it's wrong here
This traps errors but does not automatically exit on every command failure; it requires explicit handling.
- ✓
set -e
Why this is correct
set -e exits the script on any command failure.
- ✗
set -o pipefail
Why it's wrong here
This causes a pipeline to fail if any command fails, but does not exit the script automatically unless combined with set -e.
