re: Bash from scratch: learn enough bash to write your own scripts VIEW POST


#!/usr/bin/env sh

You might want to consider replacing sh with bash if you want to actually do BASH scripting. They are different interpreters, and one can lead to vastly different set of available features depending on platform you run it on, while the other will (correctly) crash if the missing features (namely BASH) is missing on the system.


I started this post to talk about shell scripting in general. but I think I think you’re right, its confusing that way. I’ll change the shebang to be bash exclusive. Thank you for the feedback!


Both are definitely valid options, just if you want to write for bash then it's better to avoid ambiguity about it. When writing with support for BSD, Busybox, etc. environments in mind (e.g. inside Alpine Linux), sh is the better option, just comes with some extra baggage.
