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

else
PS1='[\u@\h:\l \D{%a %F %R %Z} \w]\$ '
fi
unset color_prompt force_color_prompt
===custom.sh===
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.

No the colour of the prompt does not follow the window decoration, I was wondering if this isn't maybe a problem only on Fedora on Qubes and not Fedora in general. I don't have a Fedora standalone I can check on. I just found it odd that the prompt on Debian would be in colour (Green, and it is real easy to find in between a lot of other output) and on Fedora it is the same colour as the text you type. But as I was re-reading my reply here I just had another look over and I just discovered that the prompt on some of the Fedora VMs is in colour, also a bright green, and some of them are default text colour. So in essense it doesn't have anything to do with Qubes. I am a little confused though because I can swear some of the VMs that I previously check where the prompt was the default text colour now has a colourful prompt. (head scratch head scratch) It must be because of a dependency that gets installed along the way because booting the vanilla Fedora-37 template it does not have a colourful prompt. I don't install anything specific for this myself. Glad we cleared that up :-) -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
