After tens of thousands of bash lines written, I have to disagree. The article seems to argue against use of -e due to unpredictable behavior; while that might be true, I’ve found having it in my scripts is more helpful than not.
Bash is clunky. -euo pipefail is not a silver bullet but it does improve the reliability of most scripts. Expecting the writer to check the result of each command is both unrealistic and creates a lot of noise.
When using this error handling pattern, most lines aren’t even for handling them, they’re just there to bubble it up to the caller. That is a distraction when reading a piece of code, and a nuisense when writing it.
For the few times that I actually want to handle the error (not just pass it up), I’ll do the “or” check. But if the script should just fail, -e will do just fine.
