Based on recommendations in the comments, I’ve started using grepWin and it’s fantastic and free.
(I’m still a fan of PowerGREP, but I don’t use it anymore.)
I know you already mentioned it, but PowerGREP is awesome.
Some of my favorite features are:
- Right-click on a folder to run PowerGREP on it
- Use regular expressions or literal text
- Specify wildcards for files to include & exclude
- Search & replace
- Preview mode is nice because you can make sure you’re replacing what you intend to.
Now I realize that the other grep tools can do all of the above. It’s just that PowerGREP packages all of the functionality into a very easy-to-use GUI.
From the same wonderful folks who brought you RegexBuddy and who I have no affiliation with beyond loving their stuff. (It should be noted that RegexBuddy includes a basic version of grep (for Windows) itself and it costs a lot less than PowerGREP.)
