So, there are many types of shells in Linux...
Different Types of Shells in Linux
The Bourne Shell (sh) ...
The GNU Bourne-Again Shell (bash) ...
The C Shell (csh) ...
The Korn Shell (ksh) ...
The Z Shell (zsh)
I have a project where I have to put together a script for the Bourne shell, starting with shebang
But whenever I use Google to learn about some detail, I always get tons of results for
bash, which I suspect are ok to use with
sh, but not always...
So I want to tell Google, "No! Give just stuff for the original Bourne shell!". But people don't type the string "Bourne shell" into most of their web pages, so Google can't help me directly with that.
"sh" to my search query doesn't help much, it matches
.sh file extensions, and it matches
"#!/bin/sh" to my search query is somewhat helpful - but I will see only results in scripts, when sometimes the simple anwsers are presented as terminal commands (which we can then adapt for use in scripts).
I know there won't be any "silver bullet" perfect solution, but in a spirit of "tips and tricks", would any of you suggest clever ways to narrow down my results like I intend?
Or is the only solution to use a handful of authoritative Bourne shell documentation sources? If so, which ones?
