Jamf Helper Reboot Script with Deferral

[kadams]

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.

I have the rudiments of one that does it with AppleScript. It was designed around our company’s previous energy policy. While I wouldn’t use it as is, I can post it later to help with formulation of what you want to do.

Basically it was triggered at 6 pm and would check if the user was working. If not it would shutdown the computer. If so, it would give a preprescribed message from our energy management folks offering to shutdown or defer. I then had a cron script (that’s how old this is) recall it every two hours offering the same choices. It did that every two hours between 6 pm and 6 am.

Again, I wouldn’t use it as is (we don’t even use it anymore) but it might give you food for thought. I’ll post after lunch.

@blackholemac , thanks Im actually brand new to scripting. I need to find a way to get what I posted to work.

[m_donovan]

Here is one that I use. It checks if the computer has rebooted in the last 4 days. If not a jamfHelper gives them the option of to restart Immediately, 2 mins, 5 mins or 1 hour. The user then gets another jamf helper as a 1 min warning to restart. It is setup on a once a day recurring checkin policy but only executes if the last reboot was at least 4 days ago. The number of days can be edited by editing this line if [ $diffDays -ge 4 ];then to your desired number of days. It also checks for a custom logo we populate on our computers. If not present it will use a built in icon. Test, test, and test again before using in a production environment.

[drarama]

Do you have an updated script for Catalina, bigsur. was trying to get this working, 

[jloesch]

How can i edit this script to change the final reboot warning timer for 1 minute to 15 minutes ? 
Seems like you can't just edit a line when using these jamf helper scripts. 
Any help would be appreciated

[blackholemac]

by default I like @m.donovan 's script better as I never really liked mine, but it got the job done. I don't use mine anymore because I was able to persuade our energy management czar that full shutdowns as opposed to sleep don't really save power. That being said, I keep it just in case I can't win that argument. If it helps great, if nothing else, I have @m.donovan 's script to use if I'm ever forced to consider a shutdown script again.

Hey @mdonovan , I would need your script to run every day with our apple updates policy. Would I be able to configure this to do that? i know you mentioned we can change the days from 4 to anything else.

[kadams]

I tested @mdonovan script in terminal. It doesn't seem to be working for me. Am I testing it incorrectly?

[kadams]

Tested both of these and cant get any of them to run. Nothing happens at all.

[m_donovan]

When you test this be sure to change these lines as shown. The # comments out the line starting with it. This simulates a reboot older than 4 days. Otherwise the computers actual last reboot date is used. Also you will need to run it as root so if running from the desktop of your test machine I use terminal and enter sudo bash /path/to/file.sh

#today=$(date +%s)
today=$(date -v+4d +%s) ###########For Testing #############################################

[kadams]

@m.donovan. If i want this to execute immediately after running a policy, would i change the days from 4 to 0?

[m_donovan]

The 4 is used in the difference variable to decide the allowed number of days to go without a reboot. If you use the today=$(date +%s) line as is and set the diffDays comparison to 0 then it should execute every time this script is run. So if used in a policy that is on a once per day trigger the user should be prompted to restart once everyday. However, I don't think this going to happen at the same time everyday. You may get users that are prompted to restart at 3pm Monday and again at 7AM on Tuesday. You should really do some testing to see how this will impact your users.

[kadams]

@mdonovan , what im needing is starting to become a lot more difficult. I need a script that restarts computers after apple updates. All apple updates do not require a reboot. So I need a script to only execute when an apple updates requires a restart. I would need the script to execute every time the apple updates script has run.

[mm2270]

@kadams Maybe I missed it, but how are the Apple updates you're referring to being installed? Do you have a separate script that's installing those updates, and, are they first being cached from a Jamf policy, and then installed, or are you installing them using a softwareupdate command?

So you know, you can get the restart flag from a package using the installer command. For example:

/usr/sbin/installer -query RestartAction -pkg /path/to/Package.pkg

The above will return a few different string possibilities, including

None   (Means no reboot required)
RecommendRestart
RequireLogout
RequireRestart  (Most common one for pkgs that require a restart, like most security updates, etc)
RequireShutdown

Using the above, if you are caching these installers, then installing them in a script, you should be able to query for the restart action on each pkg and if any require or recommend restart, set a variable that would then initiate your reboot after the script completes the installs successfully.
Conversely, if none of the updates to be installed require or recommend a reboot, logout or other action, then don't do anything after they are all installed.

Hopefully that makes some sense.

[kadams]

@mm2270 We have this script thrown in a policy sudo sh -c "softwareupdate -ia".

[crskerman]

@m.donovan I've been playing with your script and really like the way it works. However have found that users can just ignore the initial dialog box, move it out of the way at the bottom of the screen and continue on for days. Is there a way to make it time out and just restart if no options are selected?

[jkupidura]

I know this is a little old but this is the script I am using for applying forced updates. It will automatically time out after 5 minutes and choose to delay the update if the user ignores the window. You can also choose your deferral amounts by changing a $maxdeferrals number to whatever you would like. It does delay one hour each deferment though which can be changed with a few edits. Once the counter expires or they select restart now, then the update command executes. Hope this helps.

#!/bin/bash

#set deferral counter to zero
deferral=0

#set max amount of deferments a users can make
maxdeferrals=3


choice="2"

#edit title and msg that you want displayed in the pop up window
TITLE="Restart required"
MSG="Software Updates are ready to be installed on your Mac that require a restart.

You can choose to restart now, or delay this restart by 1 hour by choosing the option below:"



#Launches pop up
while [ "$choice" -ne "0" ]
    do

    #You can choose which icon you would like to appear in the pop up here
    ICON="/System/Library/CoreServices/Software Update.app/Contents/Resources/SoftwareUpdate.icns"

    choice=$(/Library/Application Support/JAMF/bin/jamfHelper.app/Contents/MacOS/jamfHelper -windowType utility -title "$TITLE" -description "$MSG" -icon "$ICON" -button1 "Restart Now" -button2 "Delay 1h" -defaultButton 2 -lockHUD -timeout 300)


    #adds one to the deferral counter
    if [ "$choice" -eq "2" ];
        then ((deferral+=1))
        fi


    if [ "$choice" -ne "0" ] && [ "$deferral" -lt "$maxdeferrals" ];

        then sleep 3600 
        else ((choice = "0"))
        fi

    done


softwareupdate -ia --restart

[JeyT]

@jkupidura, I am testing with your script, thanks. What I am looking to do is give the user an option to defer for 2 hours each time with a maximum of 12 deferrals (24 hours) and then the update will force run. New to scripting too. So what I need to do is:

1. maxdeferrals=12 (change from 3 to 12)
2. then sleep changes from 3600 to 7200.

I don't understand the "It does delay one hour each deferment though which can be changed with a few edits." What gets delayed one hour? I thought when you click on the number 2 button it will defer for whatever your value is in the "sleep"?

Appreciate any help.

[Rohitds14]

@JeyT did you test the script with 24 hours deferral? i also wondering to test that

[JeyT]

@Rohirtds14 I have not. Waiting on the release of the new deferral feature in 10.21. Hope that fixes this. Thanks

[tc_pmg]

i tried @m_donovan script posted on 2018-04-17. My Jamf logs shows the following.

I'm not too familiar scripts and the command's syntax. Any insight on the error message would be greatly appreciated.

[BradJr]

Pretty late to the party... but the first line looks like it's looking for the .png for the Jamf Helper prompt as shown on line 162 with the variable "$useIcon". Basically you're going to want to change lines 140-148 to match the location and name of your .png for the Jamf Helper prompt

The rest of the lines seem to be looking for Jamf Helper in "/Library/Application\ Support/JAMF/tmp/" where it should be looking in "Library/Application\ Support/JAMF/bin" (Full path is "/Library/Application Support/JAMF/bin/jamfHelper.app/Contents/MacOS/jamfHelper")

I'd double check the path of all of those lines that it is set correctly to point to Jamf Helper

[tc_pmg]

Thanks for pointing those out.

I've made corrections to the script that refers to the line items. Unfortunately, running the script still produces an error.

When I look at /Library/Application Support/JAMF/tmp/, the folder only has a single file that is a Unix executable file. Could the cause be the script is not found in /Library/Application Support/JAMF/tmp/Jamf Helper Reboot Script with Deferral?

So I haven't gotten to try this myself, but it looks like it's going to need some more tweaking.

I just ran those jamf Helper app lines with the following and was able to make the prompt pop.

Since those lines are going to be read as separate commands, using a backlash "\" at the end of each will allow it to continue to the next line as if it were part of the same line. At the moment I'm not sure how that'll won't in the function call "jamfHelper" but maybe adding those will get you back on track too. Once I get it working myself, I can try to share my findings with you if you're still having errors.

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

[BradJr]

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

[tc_pmg]

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

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.

[BradJr]

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?

[bcbackes]

@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.

### 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
