Hi All

I have to be careful how I word this as the last time I mentioned it everyone assumed I am a recruiter and I got some flack for it. So let me start by assuring you that I am not one, and...

Good advice, thanks.

I might be getting ahead of myself here as I'm not able to release the current version I have working at my employers site. The code contains too many references to...

After some fiddling around I settled for this variation on an earlier post -


#! /bin/bash

sed ':start
