Answer 1

It depends if you want to run a script in background via command line, than you can use exec command: exec

Or if you want to start another thread, than you can use pthreads

If you want to have a job that executes at a certain time or in certain intervals, you can set up a cronjob. This tutorial is very helpful, and if you are on linux you can look at this documentation.
