So, I just found out about a programme called SynthShell which kind of does the work for you and gives you a nice looking shell, the thing is that this also creates some config files and other stuff in my system, instead of just one .bashrc file to edit. What would be the best way to learn to have a nice looking bash where I can just have a backup of it that I can use throughout systems?
Bash syntax - I recommend Unix Power Tools by O'Reilly, but it is more advanced so maybe start with a basic version. People look at me funny whenever I say this, but I started myself with something like Unix for Dummies. Why not!?
Keep in mind that this is no trivial task: bash is basically a programming language unto itself - it even has conditionals, loops, variables, etc. Yet SO worth it if you use Unix and want to know more what it is doing.
You also should have a basic familiarity with Unix foundationals as well, to know why something such as this is very dangerous:
export PATH="~/bin/:$PATH"
So, the easy way would be to just take the nice file, copy it wherever you want, and leave it at that. The hard way of actually understanding it may require a deeper dive into Unix. Unix Power Tools, with the picture of a drill on the cover, or maybe someone will recommend a better option but that's what comes to my mind.
Have fun!:-)
