nice: Launch a program with altered priority.
$ nice -n ${niceness_value} ${command}
try on your machine
The command "nice" is used to launch a command with a specific "niceness" value, which determines the priority at which the command is executed by the operating system. The "niceness value" is a number within a certain range, typically from -20 to 19, where a lower value indicates a higher priority.
Here is the breakdown of the command:
- "nice": This is the command itself.
- "-n": It is an option or flag for the "nice" command, followed by the niceness value.
- "${niceness_value}": It is a variable holding the desired niceness value. It is usually a number.
- "${command}": It is another variable containing the actual command that will be executed.
By combining these elements, the command "nice -n ${niceness_value} ${command}" sets a specific niceness value for the execution of the given command. This can be useful when you want to modify the priority of different processes running on the system, giving more or less resources to specific tasks.
