I’m terrible for forgetting to exit a root session after I’ve been performing administrative functions on my machine, so I looked for some way of reminding me, and found this simple solution:

Edit the /etc/bashrc file to include the following function….

function setprompt
{
local RED="[$(tput setaf 1)]"
local RESET="[$(tput sgr0)]"
if [ `id -u` = 0 ] # check if user is root
then
PS1="$RED[u@h:W]$RESET "
else
PS1="[u@h:W]$RESET "
fi
}
setprompt

This then changes the prompt colour to red (or any colour you like) when logged on as root…..
