+# Usage: "./Linux - Update TRMM agent.sh" update amd64
+# 
+# Description:
+#   This script is used from inside of Tactical RMM instances to schedule an update of a linux agent. 
+#   The script will download the update script and schedule it to run after 2 minutes, 
+#   this is done because the update script needs to stop and replace the agent files on the host.
+#
+# Arguments:
+#   update - Used to specify that the agent needs to be updated
+#   [SystemType] - Specify what type of system the agent needs to be updated on ('amd64' 'x86' 'arm64' 'armv6')
+#
+# Author: D. de Kooker (info@dcomputers.nl)
+# Sources: https://github.com/netvolt/LinuxRMM-Script/blob/main/rmmagent-linux.sh
+# Changelog: 
+#   06-09-2023 - Change the script from source to exclude the Install and uninstall part, 
+#                adjusted it so it could be run on it's own (or by scheduled task script with TRMM) to update a linux agent.
