Hi,

I'm new to Apple and JAMF and so seeking help from anyone who can. I have created policy for Adobe Reader 11.0.12. All I need is a script to add to it that will check the version at startup and install it if the current version is older than 11.0.12.

Thanks
PJ

What you will probably want to do is use two policies: one with a script that runs on startup and performs the version check, and a trigger policy that the script runs if it needs to install Adobe Reader.

Here is a snippet of how I do version checking for multi-decimal versions (Flash in this example):

#!/bin/bash

targetFlashVersion="18.0.0.232"

tar_ver_major=$(echo $targetFlashVersion | awk -F. '{print $1}')
tar_ver_minor=$(echo $targetFlashVersion | awk -F. '{print $2}')
tar_ver_sub1=$(echo $targetFlashVersion | awk -F. '{print $3}')
tar_ver_sub2=$(echo $targetFlashVersion | awk -F. '{print $4}')

flashPluginVersion=`/usr/bin/defaults read /Library/Internet Plug-Ins/Flash Player.plugin/Contents/Info CFBundleVersion`

if [ ! "$flashPluginVersion" ]; then
    echo "Flash plugin not installed.  Exiting."
    exit 0
fi

ver_major=$(echo $flashPluginVersion | awk -F. '{print $1}')
ver_minor=$(echo $flashPluginVersion | awk -F. '{print $2}')
ver_sub1=$(echo $flashPluginVersion | awk -F. '{print $3}')
ver_sub2=$(echo $flashPluginVersion | awk -F. '{print $4}')

if [ $ver_major -ge $tar_ver_major ]; then
    echo "Major version: OK"
    if [ $ver_minor -ge $tar_ver_minor ]; then
        echo "Minor version: OK"
        if [ $ver_sub1 -ge $tar_ver_sub1 ]; then
            echo "sub1 version: OK"
            if [ $ver_sub2 -ge $tar_ver_sub2 ]; then
                echo "sub2 version: OK"
                echo "Flash version $flashPluginVersion is equal to or better than $targetFlashVersion, not updating"
                exit 0
            fi
        fi
    fi
fi

echo "Flash version $flashPluginVersion is lower than $targetFlashVersion, updating"
jamf policy -trigger installFlash$targetFlashVersion
