Bash coding
 

I'd like to write a shell code that will put back the settings I make in the terminal,
i'm open to learning php except the settings i make will be for certain distributions say Debian or Gentoo, so i was considering bash coding but open to either. Would like any suggestions on which I should choose please.

Thank you.

If you are writing this to manage BASH terminals, I suspect a BASH script would be the better option.

Just my two cents.

It is unclear for me. What kind of settings is it? Do you have an example? (or even better) do you have a sample code?

Yes this too I suspected. I'm looking for a easier way to restore all my personal settings when i re-install a OS. Thanks for the help

Oh for example, some commands like shutdown isn't in the /root path so I would have to type it like /sbin/shutdown -r . That and a whole lot of other commands are default in another path, so I was weighing on whether or not I would learn php or bash scripting to customize the cmd line the way I want it. If that makes any sense

It makes very little sense and is still way too broad, but youprobably want to learn bash (and not php) if your shell is using bash.

Issue
to find out.

That would be a backup solution, so you save all of your personal settings, files before reinstall and try to restore it afterward.
From the other hand you may have a data (user) partition which will not be modified/altered during that OS reinstall, therefore there is no need to restore it (anyway, a backup would be helpful).

create a list of all the files you change for the settings you change. if you installed a new system on 2021-05-31 and changed many settings through the month of June, then scan for all system files changed in the month of June. that's a good starting list. edit it and remove file names that are not your settings. make a backup of the files named by what remains. make a 2nd backup. test your backup to be sure you can read it and get the files back out. test the 2nd backup, too.
