This was 20 years ago, but what I found was that bash is on every system. Too many shells would only have bash (or ksh) where my zsh profiles were useless. Fast forward to today and I’m hard pressed to find any containers with anything but Bourne. So bash it is!
Understood. I learned this way too, stick with a near universal standard/expectation, especially if you want to script for it and customize and if you are accessing remote machines often so you can be comfortable and productive in any situation.
P.S. just fully noticed your handle, very shell discussion appropriate! :)
