This is more a post for me than anyone else, but I thought I’d share anyway.
In our team we have a mixture of Linux and Mac users, and we are constantly editing the same files. One of the most irritating things is when a file is saved with Mac line endings instead of Unix line endings (displaying as ^M in Emacs). This happens very rarely, but on the occasion it does I can quickly convert back using the following commands on my Linux box:
$ tr 'r' 'n' < file-in-question.txt > tmp.file $ mv tmp.file file-in-question.txt
If you want to find more about the tr (Translate) program, visit the man page.
