A simple use of Applescript to get PID (unix id of processes ) and kill one Application if another is not running.
But heres a better example..
If I have one App running and I want a second app always running while the first app is running. Or when I quit the first App the second app will also quit.
You may have noticed the #!/usr/bin/osascript This is an the Applescript Shebang . Which basically allows you to write a applescript in its native syntax , save it as a applescrpt text file. And run it like a shell command.
Like any shell executable you need to give it the correct permissions to execute.
So after saving the script down as a Applescript Text file. (.Applescript). Open Terminal.app and type:
chmod 755 /path/To/foo.applescript
One of the ways I would use this now executable script. Is as a user’s Launch Agent. Launch Agents run jobs on your Mac in the background. Google or read about Launch Agents on Apples website for a better explanation.
All I want my Launch Agent to do is run the Script every 30 seconds.
I first create a plain text document in textEdit document. You can use your own flavour of plain text editing tool. And put the following code in it:
<?xml version=”1.0″ encoding=”UTF-8″?>
<!DOCTYPE plist PUBLIC “-//Apple//DTD PLIST 1.0//EN” “http://www.apple.com/DTDs/PropertyList-1.0.dtd”>
- Label name of the Launch Agent process. It would be a good idea to name the plist file the same. Here it is called com.example.dualApps
- ProgramArguments are what it says on the tin. In this case it is just the path to the .appscript to run.
- StartInterval the time interval I want the agent to run.
More info can be found at Launch Agents .
Save the com.example.dualApps.plist file in ~/Libary/LaunchAgnets as a .plist file rather than a .txt.
In Terminal.app you can then start the job.
launchctl load ~/Libary/LaunchAgnets/myfooAgent.plist
Now ever 30 seconds The script will run and either quit or launch Snippets depending if Script Editor is running or not.
To unload the Agent.
launchctl unload ~/Libary/LaunchAgnets/myfooAgent.plist
Read the Manual for more commands on launchctl
