A couple of weeks ago I came across the scenario in which although my build scripts was having linting issues, the pipeline running this script would not fail.
My investigation led me to stumble upon a nice combo of shell commands that would ensure the script to fail fast and avoid having non desired outcomes.
A neat commands combo to fail fast
set -o errexit set -o errtrace set -o nounset set -o pipefail
In short this should exit as soon as it encounters any non-zero exit code or usage of undefined variables or failed piped commands.
The one-liner command of the previous combo is:
set -Eeuo pipefail
Having this combo in my shell scripts make them safer and therefore increases my confidence when pushing a change.
