This works well, except when I'm using Silver Searcher (ag version 0.23.0, installed with homebrew) it outputs the location of ag (/usr/local/bin/ag). So if I pipe to xargs rm, ag is removed and I have to relink. I've played with the script a bit to see if I could fix it, but I'm not familiar with shell scripting. Any thoughts?
