Sure, a bash script.

People keep writing and using other alternatives (like just), which provide a very slight improvement on pure shell at the cost of installing yet another tool everywhere.

I stick with bash, write every task as a separate function, and multiplex between them with a case statement (which supports globs et al. and is very readable).

Years ago, I discovered git-rev-parse's option parsing, and it completely removed any excuse I had not to write my own personal bash scripts to a professional standard.

Now when I need a tool, I can knock it out in bash with proper option parsing, usage, etc.

bash is awful on a lot of fronts, but if you're writing code that's primarily calling a bunch of tools and mucking with their output, it's still the best thing out there I've found just due to piping syntax.

Taskfile and Justfile are pretty solid.
