Overview of Updating Unidata McIDAS-X

The Unidata McIDAS-X distribution (available in mcidasx2005.tar.gz in the UPC's passworded McIDAS FTP account) will always contain all modifications and additions made to the initial release.

The accumulated set of modifications and additions to the original distribution will always be available in mcupdate.tar.gz and in the FTP unix/2005/bugfix directory. This update file is designed to be unpacked using the Bourne shell script, mcupdate that is contained in the 2005 package directory: ~mcidas/mcidas2005/update.

After your initial Unidata McIDAS-X installation, you should periodically check the Unidata McIDAS-X Updates page for changes that you need to make to your software.

Getting and Unpacking the Update

The user mcidas should download the compressed file that has the updates that are needed:

Web download

      If you are a Registered Unidata User, and have logged into the Unidata
      web portal, you can download by holding down the Shift key and
      clicking mouse button 1 on: mcupdate.tar.gz.  Make sure to download
      it to the ~mcidas/mcidas2005/update directory!

      Alternately, you can download the update using FTP:

FTP download

Type: cd ~mcidas/mcidas2005/update
Type: ftp ftp.unidata.ucar.edu
      <user>
      <pass>
      cd unix/2005/bugfix
      binary
      get mcunpack
      get mcupdate.tar.gz
      quit

Next, run mcupdate to unpack the modified files:
mcupdate runs gunzip and tar to unpack the update file into appropriate directories.
