What do you mean? Doesn't matter if it's on premise or in the cloud(someone elses computer) - someone still has to manage it from the company's point. If you leave it to the devs it'll be a disaster.

With that said, this industry is moving fast and if you wanna keep up you need to learn bash/python or powershell on windows, eventually... this is true. Or you can move to smaller companies with fewer assets to manage.

If you say you can throw a bash script together than that's a good start. When doing that, try to understand what the author has done - check how the script was made, look up each function and try to remember what they do.

Once you remember functions you can always use that knowledge and look up syntax and arguments in the docs and start writing your own code. Bash is not a good place to start though, because it has a lot of weird syntax but python is rather clean.

Also take your time, don't think it's something you can learn within a week or month, give it 6months - year, don't push it. If you can't figure it out today, it's ok, try another day.
