7,762,257 | I'm trying to make an application that checks if this specific application is running, then kill the app after a specified amount of time. I'm planning to get the pid of the app. How can I get the pid of the app?

] | you can use `pidof` to get the pid of your application
`pidof <application name>` | If you're starting this application from script you can get the pid of the last process that was created in background by using the special variable `$!`, this value you can save on a file for later use on your shutdown function.
Below is an example:
```
nohup java -jar example.jar &
echo $! > application.pid
