Top Forums Shell Programming and Scripting Matching and Replacing file lines starting with $ Post 302913073 by Corona688 on Wednesday 13th of August 2014 03:27:41 PM

It's difficult to extrapolate what you do want from a program which doesn't do what you want.

Show some minimal input we can test with please, the output you presently get from it, and the output you'd rather it be doing. Be sure to include a line that demonstrates the problem.

I don't understand yet why it would ignore lines beginning with $... That's a regex special character, but regexes don't appear to be involved here. Did you remove any of your code or is this complete?
