nice

Execute a program with a custom scheduling priority (niceness). Niceness values range from -20 (the highest priority) to 19 (the lowest). More information: https://www.gnu.org/software/coreutils/manual/html_node/nice-invocation.html.

  • Launch a program with altered priority:

nice -niceness_value command

  • Define the priority with an explicit option:

nice -n|–adjustment niceness_value command
