jamf_postinstall_script_for_nice_updater.sh

#!/bin/bash

# postinstall script for use in a Jamf policy
# allows defaults to be tweaked from within a Jamf Pro policy
#
# parameters as follows:
#
# 4  - Start interval (hour of the day), e.g. 13 = 1pm
# 5  - Start interval (minute of the hour), e.g. 45 = 45 mins past the hour, e.g. 13:45
# 6  - Alert timeout in seconds. The time that the alert should stay on the screen
#          (should be less than the start interval)
# 7  - Max number of deferrals (default is 8 so first message says "7 remaining alerts")
# 8  - Number of days to wait after an empty software update run (default is 3)
# 9  - Number of days to wait after a full software update is carried out (default is 7)
# 10 - Custom icon path - must exist on the device before the policy is run
