Using LiveCode to shutdown, logout and restart the Mac

I wonder if it is possible to use LiveCode to perform operations as log out, restart and shut down your Mac...

Hello Mag,
I'm wandering if my last post was enough
I made it few seconds before running out of my office on Friday evening...
That said, here are some shell commands which should help you:
- halt // shutdown immediately
- reboot // restart immediately
- shutdown -h +15 // in 15 mn
- shutdown -h 22:22 // at a secific time
- shutdown -r now // reboot immediately
- shutdown -h now // shutdown immediately
- etc.
All these commands can be executed by the Livecode shell() function.
You need the sudo command as a prefix to these commands
and it will ask for your password.
Unfortunately,you can't do that only via the LC shell()
as it opens a non-interactive shell process underneath.
There, expect comes to the rescue again:
Code: Select all
get "expect -d -c" & quote &cr& \
"set timeout 1" &cr& \
"spawn sudo cp /Users/t/x.txt /" &cr& \
"expect Password: { send 42cheese\r\n }" &cr& \
"expect eof" &cr& \
"sleep 1" &cr& \
"exit" & quote
get shell( IT)
-- verify:
put "shell: " & IT &cr& the result &cr& shell("ls -alst /x.*")
By the way, there is a book of 640 pages:

Be well,

Wouldn't it be easier to do in AppleScript?

Depends of your backgroung and knowledge, no?
And then Applescript is for Mac only!

Any chance to show us how you do it?

Thanks Mag.
So, learning the finder's applescript dictionnary might be useful

Hi Thierry,
Yes, and a lot of other applications... Some other samples...
Code: Select all
tell application "System Events"
log out
end tell
Code: Select all
tell application "Finder"
sleep
end tell
Some time ago, I made simple-sample stack for iTunes, you can find here:

And here I posted a Send Email with Mail sample:

The only problem is that if you plan to deploy the app in the Mac App Store is unlikely to be accepted because of the violation of the Sandbox.

Umm, so for shutdown and sleep it's the Finder
and for log out, it's the system events..
Doesn't sound that easy for me

Well, it's the same with the shell then.
I think I've read we can use applescript in a sandbox app only to get information...
Is that true?

Hi Thierry, Database Events, Image Events, and System Events are applications that can be used by AppleScript and that run invisibly to users, every one has it's dictionary you can see them with the Applescript Editor.
The sandboxing imposes restrictions on what the application can do, I think that there si no a simple rule and the approval process perhaps it depends on who reviews the app. It may be helpful to read about the cases reported by the developers. Maybe what you say may be right. I have no experience about for now. If you find something useful to us let us know.
