This may be the wrong place to ask, but what am I missing about shells? Other than executing commands, what do you do with them?
You can do most things by combining simple cmdline tools. E.g. filter out some specific lines from all files in a directory, get the value after the second
:, write those to another file and then sort, deduplicate and count them.This may sound complicated, but it's pretty easy and fast if your are familiar with a shell. To be that efficient with your shell you want it to actually be powerful and not just a plain text input. Also writing cmdline tools is rather easy compared to a usable GUI tool.
Genuine question: why not use grep, awk, sed, or any of the other gnu tools that can already do that?
That's what I meant, using your shell to run command line tools to solve your issue at hand. And having a powerful shell with e.g. context dependend autocomplete (and a lot more) helps to speed up that task.
