how to set up su message
 

Hello,

I would like to set up su message on my linux machine, I'm running archlinux. This is an example of what I want:
user@machine:su
password:******
Super user mode is enabled
root@machine:

how about this:

This would only invoke bash with root. I checked man pages of bash, but it doesn't seem to be anything in there or maybe i just couldn't see it.

don't know if there is a dedicated place for doing this, but it should probably be possible to do this through a bash function? (so a function in your .bashrc) something like this (not on Linux now so can't test it):

I don't think that will work, as the echo statement will only be executed once su has finished.

I think there is a small mishmash in your question. If you want to enable super user mode permanently than you should just log in as root. The su command has been created to execute something as root, but without permanent enabling su mode.

I'm sorry, maybe I did not make it clear, what I need, at that moment when I log in as superuser, I want a message to be prompted, how can I add or edit that message?

many people set up something like this through their bash prompt. so for example your regular prompt would be this:
name@linuxbox $

and your root prompt would be this:
name@linuxbox #

when you add colors, put the root one in red so it distinguishes itself.

i know this is not what you are asking, but it accomplishes the same goal.

In the file /root/.bashrc add a line:

echo Super user mode is enabled!!!!!!!!1

Thanx, that worked. P.S. I had to create that file myself, it wasn't there

The .bashrc file is optional. It's handy to have one and put aliases and things in there. For example, you could put alias ll="ls -la"

Yeah, I checked out ordinary users .bashcr and I found a lot of interesting stuff there :)
