Change nice level of currently running script

Question

I would like to change the nice level of the currently running script:

#!/bin/bash

nice_it ( ) {
    nice
    ps -o "%p %r %y %x %n %c %a"
}

nice_it

That does not work, since nice tries to change the nice level of the command started by it.

Is it possible to achieve this in bash?

This is pretty trivial.

Sure, that is it. In some systems, `-n` is not accepted. – blueFast Sep 14 '12 at 13:51

For those who don't know, `$$` is the current shell process ID. – Daniel F Mar 01 '19 at 11:50
