A PID is assigned when the process is created i.e. when your script is executed and will not be the same if you run it again. Most services create a pid file which is deleted when it is stopped by the init system.

So can you explain why you want to use the PID as part of the file name? You can find its pid using the pidof command.

The pid is $$ so you can create a filename as

Code:

FIL=$$.txt
