What command is used to set the scheduling priority of a process?

The command used to set the scheduling priority of a process is "nice." This command allows users to launch programs with a modified scheduling priority. By default, processes are executed with a priority of 0, but using the nice command, you can start a process with a higher or lower priority by specifying a value from -20 (highest priority) to 19 (lowest priority).

For example, running nice -n 10 myprocess would start "myprocess" with a priority level of 10, which is lower priority than the default. This can be especially useful in scenarios where you want to ensure that a process does not consume too much CPU time, allowing more critical processes to have the resources they need.

While "renice" is related to process priority, as it is used to modify the priority of an already running process, it does not directly set the priority at the time of process creation, which is what "nice" does. The "ps" command is used to display information about running processes, and "kill" is utilized to terminate processes, neither of which involves setting process priorities.
