bash

https://mywiki.wooledge.org/BashPitfalls https://mywiki.wooledge.org/BashPitfalls#set_-euo_pipefail recommends against set -e because of the various pitfalls especially in conditional evaluation and option pipefail and recommends own error handling instead. http://redsymbol.net/articles/unofficial-bash-strict-mode/ and http://redsymbol.net/articles/unofficial-bash-strict-mode/#short-circuiting

set -euo pipefail; shopt -s failglob # safe mode
