Hi Zach, I suspect that however you unzipped the 3.6.2 zip file, the program you used turned all line-feed "\n" characters into carriage-return line-feed "\r\n" combinations for line endings, and the Cygwin tools don't understand the carriage-return characters. Maybe you could fix your WinZip options to not do this, using the following steps 1. Open WinZip Classic. 2. Select Options > Configuration > Miscellaneous tab. 3. Uncheck the 'TAR file smart CR/LF conversion' box. The box remains unchecked until it is checked again. 4. Unzip the file again. Please let us know if this fixes the problem ... --Russ Russ Rew UCAR Unidata Program address@hidden http://www.unidata.ucar.edu Ticket Details =================== Ticket ID: UCS-286775 Department: Support netCDF Priority: Normal Status: Closed
