Having been a Mac holdout in various Wintel companies for the last 15
years, I found it simplest to write an app to fix these kinds of problems.
You can find this piece of $10 shareware at:
http://www.lgosys.com/products/stripper.html
Select the radio-button for the kind of line-endings you want (Mac OS X =
LF, Mac OS 9 = CR, Windows = CR+LF), then drag one or more text files onto
the application window. Stripper doesn't care what kind of line-endings are
present in the original files. Neither does it care if a file has a mixture
of line-endings. Stripper doesn't even care if some twit of a Windows
programmer has created lines ending in LF+CR instead of the usual CR+LF.
Stripper simply conforms all the line-endings in the file for the target
environment.
If you've got a ton of files to convert and a multi-processor Mac, Stripper
will even use both processors to churn through the task (many thanks are
due here to Messrs Anguish, Buck and Yacktman for their excellent book
including the thorough explanation of Distributed Objects and threading).
