I am installing a custom X11 application. As part of that installation, I want to check if the latest version of XQuartz is present, and if not, install it.

Using Packages, I imported the XQuartz package, and set it as a custom install choice. I then added a requirements entry for that package, using the “Result of External Script” option. I set the options to look for a return value “equal to” 0, and if that requirement is not met, to “make this choice unelectable” and add a tooltip.

Below is my script, the XQuartz package in the custom install screen is selected and available in all cases, I was hoping someone could help me determine why this isn’t working.

<script> #!/usr/bin/env bash

# Package Title: Safeword SofToken II 2.2.0 # Author: Conor Schutzman <cschutzm@cisco.com>

if [[ -e /Applications/Utilities/XQuartz.app ]]; then XQuartzVersion=$(defaults read "/Applications/Utilities/XQuartz.app/Contents/Info.plist" CFBundleShortVersionString) if [[ "$XQuartzVersion" = "2.7.5" ]]; then exit 1 else exit 0 fi fi exit 0 </script>

I don't fully understand what that script is checking for or what is going wrong, but there is one detail that jumps out to me. According to the man page for `defaults`, if you wish to read an arbitrary file, you specify the full path, without the '.plist' extension. However, in the above code, the '.plist' extension is included. Hope that helps, - Andrew Keller _______________________________________________ Do not post admin requests to the list.
