cgexec: Execute a process in a given cgroup with given controller.
$ cgexec -g ${controller}:${cgroup_name} ${process_name}
try on your machine
The command "cgexec -g ${controller}:${cgroup_name} ${process_name}" is used to execute a process within a specified control group (cgroup).
Here's what each component of the command means:
- "cgexec": This is the command used to execute a process within a cgroup.
- "-g": This option is used to specify the cgroup controller and cgroup name that the process should be executed within.
- "${controller}:${cgroup_name}": This is a placeholder for the actual cgroup controller and cgroup name values. The controller represents the specific subsystem or resource that the cgroup controls (e.g., cpu, memory, etc.), and the cgroup name represents the specific grouping or hierarchy within the controller. You need to replace "${controller}" and "${cgroup_name}" with the desired values. For example, if you want to use the cpu controller and the cgroup name is "mygroup", you would replace this placeholder with "cpu:mygroup".
- "${process_name}": This is a placeholder for the actual name of the process you want to execute within the specified cgroup. Replace "${process_name}" with the name of the process.
Overall, this command allows you to restrict a process to a specific cgroup, which means it will have resource limitations or sharing characteristics based on the cgroup's settings.
