`set -e` is almost never what you want in your scripts. It means "silently exit immediately if there are any u handled non-zero exit codes". The thing that trips most people up on that is subshells when your trying to catch output into a variable, if it gets a non-zero exit code your entire script suddenly exits.

`set -e` really only makes sense if you setup a trap to also print what line you exited on, and even then only for debugging (e g. `trap 'echo "ERROR: Line $LINENO" ERR'`)

Conversely, `set -o pipefail` should be set in every script. It makes scripts with pipelines do what you expect, and the whole string of pipeline commands gets set to an error if any of the commands inside of it exit with an error. Default behavior for historical reasons is still to ignore all exit codes except the last command in a pipeline.
