More neat bash prompt for Debian

[nataraj-hates-MS-for-stealing-github]

I use perlbew with Debian, and first thing I miss is ability to quickly see what perl I am currently using. Would be great to have it in command prompt. Like that:

I make this with a nasty hack for personal use for now:

--- perlbrew.pm.orig    2024-12-10 13:07:18.187557095 +0300
+++ perlbrew.pm 2024-12-10 15:17:18.303853634 +0300

         PERLBREW_VERSION => $VERSION,
         PERLBREW_PATH    => $self->root->bin,
         PERLBREW_MANPATH => "",
-        PERLBREW_ROOT => $self->root
+        PERLBREW_ROOT => $self->root,
+       PROMPT_COMMAND => 'debian_chroot=$PERLBREW_PERL',
     );
 
     require local::lib;

It is bash-specific, and Debain-specific. And do not treat nicely other PROMPT_COMMAND possible values.

But if you like the idea, and would accept such patch. I can do more neat version of the patch, that do it in a good way.
