For anyone getting a “unexpected operator” error on startup please try changing the default shell
from:
#!/bin/sh
to:
#!/bin/bash
this fixed the problem for me on my Ubuntu 8.04 box

Anyone have a windows equivalent?

I made a slight modification to the cecho function so the output can be optionally directed to a file:

[ -t 1 ] && echo -e “$color”
echo -e “$message”
[ -t 1 ] && tput sgr0 # Reset to normal.
[ -t 1 ] && echo -e “$black”
return

(I also changed the yellow and green settings because I can never read yellow on my xterm window.)

bushido:

The problem you are having is that you are missing some of the utilities required by the script. You’ll have to install the missing utilities, such as bc.
