This article seems to have been started from the position of "I want `set -euo pipefail`" and the points are just geared towards it. And those options have big issues! `-e` ("errexit") can just kill a script for no obvious reason, and doesn't even give a good error to figure out what happened. `-o pipefail` makes it worse by causing pipelines to sometimes fail depending on how much input was buffered - the classic example is `something | head -n 1`. It also doesn't give a proper error, and with errexit this kills the entire script. `-u` is probably okay, but also triggers for `$1` and friends, so it basically requires you to write `${foo-}` everywhere. And if you've done that, you can still misspell your variable name. See http://mywiki.wooledge.org/BashPitfalls#set_-euo_pipefail http://mywiki.wooledge.org/BashPitfalls#set_-euo_pipefail
