#            Name:  update-all-apps.sh
#     Description:  Cycles through all third party updates in Jamf and runs them if
#                   needed by the target Mac.
#          Author:  Emily KW
#        Modified:  2019-01-23
#           Notes:  Results/output sent to /var/log/jamf.log.
#                   Does not include patch policies. The final recon, however, will by 
#                   default check for patch policies, but will not run them automatically
#                   unless you configure patch policies to install automatically.
#
#                   Usage:
#                   - Set any update policy in your Jamf Pro Server with a custom trigger
#                   - Add all custom triggers on separate lines to the APPUPDATE section
#                   - Add this script to a policy with its own custom trigger and/or
#                     make available in its own Self Service policy for people to use
#
#                   Room for improvement:
#                   - Close each app if the update is required.
