I use a custom color prompt for my bash shell. I had to use different
methods in my Fedora and Debian qubes to get the prompt I wanted. It's a
little tricky because you have to check and see how the system files setup
the $PS1 file. Because I wanted the same definition in each of my qubes I
ended up creating a /etc/profile.d/custom.sh file to define the prompt in
Fedora templates to set the prompt in each appVM based on that template.
The code based on some adapted Debian or Ubuntu code. There is also a
bunch of code to setup definitions for colors and other terminal escape
sequences.
My custom.sh produces prompt like:
[user@docker-fed-37:2 Fri 2023-05-05 17:35 GMT /etc/profile.d]$
where
user@docker-fed-37 is green
/etc/profile.d is bright_blue
the :2 represents the terminal number where numbering starts with :0

Another alternative I explored is the setup the above or similar file in
the appVM .bashrc.d file.
Unfortunately, the Debian default overrides any $PS1 string defined
/etc/profile.d/custom.sh so I define and export a $CUSTOM_PS1 environment
variable and then use it appropriately in my Debian .bashrc to set the $PS1
string. Also note that the term-control-colors function doesn't work in
Debian login shell and the "my_" variable definitions can be used instead.
