renice: Change priority of a running process.
$ renice -n ${niceness_value} -p ${pid}
try on your machine
The renice
command is used to modify the priority (or niceness) of a running process on a Unix-like operating system. The command syntax you provided, renice -n ${niceness_value} -p ${pid}
, renices (changes the priority of) a process with a specific process ID (PID) to a specified niceness value.
Here's a breakdown of each element:
renice
: The command itself, which is used to change the priority of a process.-n ${niceness_value}
: The-n
flag specifies the new niceness value for the process.${niceness_value}
should be replaced with the desired numerical value representing the priority. A lower value indicates a higher priority, with -20 being the highest and 19 being the lowest.-p ${pid}
: The-p
flag is used to specify the process ID of the process that needs to be reniced.${pid}
should be replaced with the PID of the target process.
In summary, this command modifies the priority of a specific process identified by its PID (${pid}
) to the desired niceness value (${niceness_value}
).

never run a command you are not sure if it is safe.
