I cannot reproduce this, either from a bash prompt or from cmd using your .bat file: $ cat a a a a $ cat somedir\\b a b a $ diff a somedir\\b 2c2 < a --- > b The batch file outputs: This batch file: diffbugtest.bat diff (GNU diffutils) 2.8.7 Written by Paul Eggert, Mike Haertel, David Hayes, Richard Stallman, and Len Tower.

There was no attached cygcheck so I don't know how your mounts are setup but from what I've read, using textmode mounts with tools like cvs and diff is a recipe for disaster.
