So, very rarely I need to change the line endings for a large set of files scattered across a bunch of directories. Sometimes there are few enough files that I just do it manually, but today I really wanted to do a large batch of them recursively. I wound up using this in a terminal:
cd /path/to/change/line/endings
find . -type f -exec perl -pi -e 's/\r\n?/\n/g' {} \;
Worked like a charm. Found this here.
