I think I ran across a bug in a batch file because it was written with unix line endings. Is this a known problem with cmd.exe running batch files in windows?
This really isn't a "bug"... as it is by-design. Windows new-lines are defined as "\r\n" ... or a "Carriage Return" and "New Line" combination... whereas *nix flavors prefer omitting the carriage return. You should always use "\r\n" in anything in Windows where possible. Anything else may be interpreted incorrectly... and cause a great deal of unexpected results.
