Color bash prompt with time and cwd

Bash prompt (yellow for "foreign" systems):

    xterm*)
        TITLEBAR='\[\033]0;\u@\h:\w\007\]'
        ;;
    *)

Type "pow" to see power and sensor status

This is my personal convention on machines I use regularly. The aliases above include one version of this; see also other ways to implement it.

Console clock

Below is a script for an upper-right console clock. It can be called bgclock but I don't know the best way to make it put itself into the background. Could use raw ANSI codes rather than tput, but I'm lazy.

#!/bin/sh
while [ 1 ]
do
        COLS=$((`tput cols` - 8))
        tput sc; tput cup 0 $COLS; date +%H:%M:%S; tput rc
        sleep 1
done
