I'm trying to have the Bundle function "Edit Text File" do a search and replace using expressions.

I want it to replace the text "VAR" with %computername:~3,3%
(:~3,3 tells it to skip the first three characters of the PC name and use the next three. Basically pulling the middle of the PC name out to designate out site)

This command works in DOS, but the ZCM bundle just pumps in the literal text. Anyone?
