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


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


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.

renice -n 10 $$
  • Sure, that is it. In some systems, -n is not accepted.

    For those who don't know, $$ is the current shell process ID.
