Here is a good example from ksh .profile for Solaris

################################################################################
# Name: .profile
# Description: This is root's profile. Login shells source this after
# /etc/profile. It is used to define root's environment.
# All non-environment configuration will be done in the
# shell specific resource file.
# Special: ENV= is specific to ksh to indicate the name of it's
# resource file. Bourne shell ignores this.

Keep Ryan's name in it - he did write it afterall.

I stumbled upon this site and thought I could give Gary’s promt a try. I like it a lot and modified it a bit for use with colorful terminals. Here’s what I use now:

PS1="\[33[01;32m\]\u@\h \[33[01;31m\]uid:\${UID} \[33[01;34m\]\d \[33[01;33m\]\w \[33[00m\]\t \[33[01;32m\]>\[33[00m\] "

The uid display is arguable I guess and I use it only on the root prompt.

Cheers !
