How to apply a terminal script using ssh to all users

scriptssh

I need to disable Google chrome's print preview option using the script
"defaults write com.google.Chrome DisablePrintPreview -boolean true -contributed by CutMaster", to a mac using ssh and apply this to all users.

The script above only works when you enter it when logged in as a user. However, I do not have access to the user's account but I do have access to the admin account.

Your help is much appreciated.

Use the `sudo` command

The command is sudo -u username command

So, after you SSH in as the admin, issue the command:

sudo -u <username> defaults write  /Users/<username>/Library/Preferences/com.google.Chrome.plist D
isablePrintPreview -boolean true

That will set the preferences value for the particular user you are interested in without having to know their password.

I personally checked this on OS X 10.11.4 using an account called "testguy". I was able to SSH into the machine, set the preferences using the command you provided and verify that it was set by issuing the command:

sudo -u testguy defaults read  /Users/testguy/Library/Preferences/com.google.Chrome.plist Di
sablePrintPreview

The response was 1 (true)

How to enable SSH without using the gui or apple script on snow leopard

You can enable SSH from the Terminal with:

sudo launchctl load -w /System/Library/LaunchDaemons/ssh.plist

(note that you need to run this as an admin, and it'll ask for your admin password, which won't echo as you type.)

Apple tv ssh script automation

you could ssh root@apple-tv.local killall AppleTV, also you might want to change your passwd from the default. As for a icon, you could but the above into a file and name it with a .sh extention, which could then be 'clicked on'.

If you don't want to be prompted for a ssh passwd, set up some ssh keys.

Setting up ssh keys

If you already have a key on your computer, skip to step 2

ssh-keygen -t rsa and follow the the prompts. If you use a passphrase, you'll want to set up ssh-agent.
Copy contents of ~/.ssh/id_rsa.pub to ~/.ssh/authorized_keys on the tv.
chmod go-rwx ~/.ssh/authorized_keys
