I'm attempting to create a regular expression to use as a filter in DeltaWalker. I want to identify the files that had code updated in a library that our project uses, but the library source files have all had a single line, Copyright (c) 2008 - 2009 changed to Copyright (c) 2008 - 2010. I'd like to ignore those lines because otherwise most files contain the same source code.

^.*Copyright.*$
matches an entire line if it contains the word Copyright.
^(?:(?!Copyright).)*$
matches an entire line if it does not contain the word Copyright.
Which one you need to use depends on how filtering works in DeltaWalker.
EDIT: If you only want to match lines that follow the specific format you quoted, then you could use
^\s*Copyright\s*\(c\)\s*\d+\s*-\s*\d+\s*$

Thank you. Curious, DeltaWalker's filtering doesn't seem to be working. Not being familiar with regular expressions, I thought I'd test your solution with: find . -exec grep -Hn '^.*Copyright.*$' {} \; in OS X's Terminal. It works perfectly with grep, but not with DeltaWalker filtering. – Nov 24 '10 at 17:54

If you're not wanting the 2010 stuff, you can do this.
^.*Copyright \(c\) 2008 - 2009.*$

Don't know much about DeltaWalker, but this regexp should will match both "Copyright (c) 2008 - 2009" and "Copyright (c) 2008 - 2010"
/Copyright \(c\) 200(8|9) - 20(09|10)/
