renice: Change priority of all processes owned by a user.
$ renice -n ${niceness_value} -u ${user}
try on your machine
The command "renice" is used to modify the priority of a running process. It allows you to change the "niceness" value of a process, which affects how much CPU resources the process gets.
Here is a breakdown of the command:
- "renice" is the command itself that modifies process priority.
- "-n" flag specifies the niceness value that you want to set for the process.
- "${niceness_value}" is a placeholder that should be replaced with the desired niceness value. Niceness values range from -20 to +19, where lower values indicate higher priority.
- "-u" flag specifies the user whose process you want to modify.
- "${user}" is a placeholder that should be replaced with the username of the user whose process you want to modify.
By executing this command with the appropriate replacements, you can adjust the priority of a specific user's process and control how much CPU time it receives.
