You have used "gunzip -d" instead of the "gunzip -c". You also have an incorrect ";" in the file name. You have downloaded a binary distribution, which does not contain source code. Unpack the distribution using: gunzip -c gempak_upc_linux5.10.3.tar.gz | tar -xvf - After unpacking, edit the Gemenviron or Gemenviron.profile depending on your shell as described here: http://www.unidata.ucar.edu/software/gempak/GEMPAK/Install_GEMPAK.html After sourcing the environment to your shell, see the online tutorial here: http://www.unidata.ucar.edu/software/gempak/tutorial/ Steve Chiswell Unidata User Support Ticket Details =================== Ticket ID: XZP-151741 Department: Support GEMPAK Priority: Normal Status: Closed
