Shell scripts are one of the things that makes Linux what it is. They’re relatively easy to create, powerful, etc. It was the thing that drove me to it from Windows in the first place.
One thing I would recommend against is creating dozens of utility scripts and/or aliases for things you run frequently. I have found it’s much better in the long-run to simply learn the “proper” commands and switches. If you use them often enough you start to type them very quickly. When you create helpers you start to learn your own ecosystem and will be lost on any system that doesn’t have your suite of helper apps installed.
There are exceptions to this to be sure (e.g. I always alias ‘l=ls -FhlA’) but I would specifically avoid the podup and poddown ones myself. I’ve gotten very quick at typing “docker run -it --rm foo” just by rote repetition.
You’re free to do as you like though. Maybe you’ll only run Linux on your own desktop so that’s all that matters. But something to keep in mind. I would at least learn the commands very well first and then later alias or script them for convenience.
