43.2. One Argument with a cat Isn't Enough
cat Section 12.2
% cat filename | tr -d '\015' > newfile
A wise man once said: if you find yourself calling cat with just one argument, then you're probably doing something you shouldn't.
The command line above only uses cat to feed the file to the standard input of tr. It's a lot more efficient to have the shell do the redirection for you with its < character (Section 43.1):
% tr -d '\015' < filename > newfile
