SCP shutdown system

There is a shell command for doing shutdown. Unsurprisingly, it's called 'shutdown'. In Terminal its man page is:

Code:

man shutdown

You could also use AppleScript to initiate shutdown, using the osascript command:

Code:

osascript -e 'tell app "System Events" to shut down'

Use AppleScript Editor to open the scripting dictionary of System Events, and look at the Power Suite of commands.

 

I don't understand what you're expecting it to do.

If the file transfer is in progress, then a shutdown will abort that transfer without completing it. That makes no sense. I would think you want the transfer to complete.

If the shutdown command is executed after the file transfer, then of course it's going to ask for the 'sudo' password then.

Again, I don't know what you're expecting it to do.

If you have an application open with unsaved data, then of course you should expect a shutdown to ask you to save the data. If you don't want that to happen, then save the data before starting the transfer and shutdown.


Perhaps you should think about building yourself a Workflow in Automator that performs the file transfer in Terminal, waits for it to complete, then quits Terminal. Only then do the script that tells System Events to shut down.

If the file transfer is a single shell command, then you can script that as a single action in Automator, too. That might make more sense than telling Terminal to do it. Hard to say, since you haven't explained exactly what you're trying to accomplish.

I suggest using Automator because Automator workflows are more clearly a sequence of action steps, which you don't seem to realize is also how command-lines work.

 

If you're doing the scp from the command line already, then it's quite easy. Just run the command like:
sudo shutdown -h `scp file remotemachine:/path > /dev/null ; echo "now" `

This will first run the scp command, then the shutdown command when it is done.

You'll also have to add a line to /etc/sudoers so you won't have to type your password . It should look like:
prramesh localhost = NOPASSWD: shutdown -h now

No guarantees on the correctness of the sudoers line.

 

Ok, the correct line for the sudoers file is:
prramesh localhost = NOPASSWD: /sbin/shutdown
where localhost is the actual name of your computer, and prramesh is the username you use on your computer.
