Anyone has a reboot script that Allows deferral and uses Jamf Helper?. Would like to attach it to an apple updates policy. After the policy runs, it should prompt the user to restart the machine. The user should be allowed to postpone that reboot at least once before it reboots on its own. I have seen some that uses CocoaDialog. We cant/wont use Cocoadialog here at our company.

Jamf Helper Reboot Script with Deferral

After adding the space backslash at the end of each line, at least now my log only shows one rogue line vs 9. It's promising now but it's starting to look as if the script is unable to find the file in the tmp subfolder.

Script result: /Library/Application Support/JAMF/tmp/Jamf Helper Reboot Script with Deferral: line 159: -windowType: command not found

Mind if I see lines ~138-168 from your script one more time since the edits?

Sure. Here are those lines.

if [ $diffDays -ge 4 ];then

#echo "4 days or more. Running Reboot script"
file=$(find /usr/local/jamfconnect/pmglarge.jpg)
if [ ! -z "$file" ]
then
useIcon=/usr/local/jamfconnect/pmglarge.jpg
#echo "found"
else
useIcon=/System/Library/CoreServices/CoreTypes.bundle/Contents/Resources/AlertCautionBadgeIcon.icns
#echo "not found"
fi

else
#echo "3 days or less. Exiting"
exit 0
fi

jamfHelper()
{
"/Library/Application Support/JAMF/bin/jamfHelper.app/Contents/MacOS/jamfHelper" 
-windowType utility \\
-title "PMG Mac Systems Admin" \\
-heading "It's time to reboot" \\
-description "This computer has not restarted since $lastBootFormat. Restart now or choose a delay option." \\
-icon "$useIcon" \\
-iconSize 110 \\
-button1 "Delay" \\
-button2 "Restart Now" \\
-showDelayOptions "120, 300" # 2 minutes, 5 minutes \\
}

Sure. Here are those lines.

Looks like you're missing a backlash after the first line 🙂 and you also won't need the backlash after the last line with the "showDelayOptions" as the command technically ends there. That'll also cause it to stop in it's tracks.

Have a look at this for reference

That worked!! Thank you so much for tips and the reasoning behind it. That makes learning this very helpful.

You're very welcome! Glad we could get that working 👍 In the spirit of breaking it down. Here is essentially how terminal would run the line with those backlashes in place.

This is also another format you could use in the script to have it run that Jamf Helper prompt. (All in the same line). Hope that helps even more, have a great day!

That is also a "good to know" way to use a script. I personally prefer the separate lines to make things easier to read than to horizontally scroll. But to each their own and your knowledge has been passed to me in a positive way. Cheers!

Do any of your gents have and still use a full working version of this Reboot script?

@rcole It's been a couple of years since I tested the one I'm using. It's one I got from this other post. However, the last time I tested it things worked as designed. Here's the settings I have configured (I changed the defer times). I was going to setup a policy and smart group to target devices that hadn't rebooted in the last 7 days and run this script on them. I hadn't gotten around to implementing it yet since I first tested it.

#!/bin/bash

### This is a JamfHelper Script which will be used to notify user if they have not restarted the computer in 7 days

### This script will give the user options how to proceed (now, 1 min, 5 min, 30 min 1 hr, 2 hrs as an example)

### This is needed as staff members tend not to restart their computers often

### This script is called from another script that checks uptime

##################

### Using Jamf Helper is cool
