Making changes on one Mac can easily be made using the GUI interface, but managing a large number of workstations (especially when performing the same operation) can unnecessarily consume too much of your time.
I recently had to add a bookmark for a SharePoint location for Microsoft Office 2011 applications. Doing so on one Mac was very easy by using the GUI interface but deploying the same change to 100 Macs would not have been possible without taking a few days and a few extra white hairs.
Thanks to Darren Wallace, I managed to complete the task with just a couple of terminal lines. I used the PlistBuddy terminal utility to edit the com.microsoft.office.plist file in my Library/Preferences folder.
Great job, I thought to myself. But how do I edit this file on every Mac and in every users’ home folder?
Luckily, the customer had a Casper solution in place that meant I just had to write a script in Bash and let Casper deal with the hard work.
Then I remembered that David Acland, my Technical Director, had written a previous blog about writing data into existing home folders as part of an installation package. I jumped on the web, found the blog, and that was it. I had a piece of art, which could serve as a base for my script.
Recycling scripts is an essential skill in the scripting world. What makes things even easier is that David’s script had invaluably helpful comments under each line. I easily found what I didn’t need and deleted those sections, which essentially made the script universal.
In the loop, I inserted my PlistBuddy commands, and that was it. Job done. In a couple of hours, I had a script that will add SharePoint locations for every user on every Mac in a medium sized organisation.
Here is what the script looks like:
#!/bin/sh counter=`ls /Users | grep "[A-z 0-9]" | grep -c -v -E 'Shared|Guest|.localized|.DS_Store'` # Outputs the number of folders in the /Users directory, excluding the Shared & Guest directories killall cfprefsd # Restarts the process to allow plist changes to be applied while [ $counter -ne 0 ] # Loop start do targetFolder=`ls /Users | grep "[A-z 0-9]" | grep -v -E 'Shared|Guest|.localized|.DS_Store' | head -$counter | tail -1` # Gets the target folder name. We prefer an ls loop as otherwise you will need to work around non-mobile AD accounts #and using ls on the /Users folder (or wherever the home folders are on the target Macs) ensures that you only get #real device “users” and not all of the system accounts. /usr/libexec/PlistBuddy -c "Add :favoriteslist:Children:0 dict" /Users/$targetFolder/Library/Preferences/com.microsoft.office.plist #Adds new dictionary under favouritelist, under Children /usr/libexec/PlistBuddy -c "Add :favoriteslist:Children:0:Name string "$4"" /Users/$targetFolder/Library/Preferences/com.microsoft.office.plist #Adds the string Name in the newly created dictionary with a variable in its value $4 that can be replaced by a constant value. #The $4 will allow Casper to use custom labels preset in a policy. /usr/libexec/PlistBuddy -c "Add :favoriteslist:Children:0:URL string "$5"" /Users/$targetFolder/Library/Preferences/com.microsoft.office.plist #Adds the URL string in the newly created dictionary with a variable in its value $5 that can be replaced by a constant value. #The $5 will allow Casper to use custom labels preset in a policy. counter=$(( $counter - 1 )) # Reduces the counter by 1 done killall cfprefsd # Restarts the process to allow plist changes to be applied exit 0
