2013-06-15 Automatic updating of Google Drive

On my bog standard MacBook Pro, it seems that there's an update problem with Google Drive. It fails to automatically update itself. Perhaps it has to do with the fact that I'm running as a standard user, not the Administrator that OS X supplies by default.

I found others who share this problem, and decided to write a little shell script that checks the current version against the new version. Run it once a week and see whether you need to update or not.

  DESTMOUNT="Install Google Drive"
  wget --quiet --no-check-certificate -O "$DEST" "$URL"
  hdiutil mount -quiet "$DEST"
  PREV_VERSION=$(/usr/libexec/PlistBuddy -c "Print :CFBundleVersion" "/Applications/Google Drive.app/Contents/Info.plist")
  [ $? -ne 0 ] && exit 1
  VERSION=$(/usr/libexec/PlistBuddy -c "Print :CFBundleVersion" "/Volumes/$DESTMOUNT/Google Drive.app/Contents/Info.plist")
  [ $? -ne 0 ] && exit 1
  #echo "old version: [$PREV_VERSION], new version: [$VERSION]"
  if [ "$PREV_VERSION" != "$VERSION" ]; then
      echo "Please install update!"
      echo "Google Drive is up to date."
      hdiutil unmount -quiet "/Volumes/$DESTMOUNT"
      rm "$DEST"

Copy the script into a file called "checkGoogleDriveVersion.sh" and put it in your Documents folder, for example. Drop to the commandline and make it executable:

  $ cd Documents
  $ chmod ugo+x checkGoogleDriveVersion.sh

Give it a test drive:

  $ ./checkGoogleDriveVersion.sh

If it finds that you need to update, switch to finder and see that there's an opened DMG. Stop Google Drive, install the update and have fun.
