Cogratulations coreplayer2.  You are the first one to teach me something cool this year.  I have so often wished for the -= operator but, since I typically don't use "let", I never new it was there.  I guess one of the long term hazards of BASIC-as-a-first-language is the deeply ingrained notion that "VAR=VALUE" is exactly the same as "let VAR=VALUE", which clearly is not the case in shell scripting.

Code: [Select]

num=`expr ${NUM} \- 1`


Code: [Select]

let num-=1

Thanks for demonstrating such a useful tool.

Ha ha!  Your welcome, glad it was enlightening.  Am trying to learn bash as fast as possible, btw this "let" which I found quite interesting, was able to use on a project I'm currently working on.  So whilst it was still fresh in mind wrote a countdown the new year.
