I like having this in my .bashrc:

PS1=’\[\e[32m\]\t \h:\W \$ \[\e[m\]‘
[[ $EUID == 0 ]] && PS1=’\[\e[31m\]\t \h:\W \$ \[\e[m\]‘

(1) it colors the prompt green when I’m logged in as me, but when I have su’d into root, it goes red — a very useful distinction!

(2) it shows the current time in 24hr HH:MM:SS format due to the \t. There are lots of times when I run a command and walk away, and I would like an approximate idea of how long it actually took. (If I want “exact”, I’ll use the time command, but that’s not always needed)

Ramesh,
An unrelated question but specific to Ubuntu… I heard that there’s a directory copy installation available for Ubuntu. The last time I tried the normal install a couple of years back, it was scary. Any thoughts on this simple installation procedure.

May be you could post an article about that as well.

Cheers,
Ajith
