cgexec

CGEXEC(1)							 libcgroup Manual							 CGEXEC(1)

NAME

       cgexec - run the task in given control groups

SYNOPSIS

       cgexec [-h] [-g <controllers>:<path>] [--sticky] command [arguments]

DESCRIPTION

       The cgexec program executes the task command with arguments arguments in the given control groups.

       -g <controllers>:<path>
	      defines  the  control  groups  in which the task will be run.  controllers is a list of controllers and path is the relative path to
	      control groups in the given controllers list.

	      This flag can be used multiple times to define multiple pairs of lists of controllers and relative paths.  Instead of  the  list	of
	      all mounted controllers, the wildcard b"*b" can be used.

	      If this option is not used, cgexec will automatically place the task in the right cgroup based on /etc/cgrules.conf.

       -h, --help
	      Display this help and exit.

       --sticky
	      If running the task command with this option, the daemon of service cgred (cgrulesengd process) does not change both the task of the
	      command and the child tasks. Without this option, the daemon does not change the task of the command but it changes the child  tasks
	      to the right cgroup based on /etc/cgrules.conf automatically.

EXAMPLES

       cgexec -g *:test1 ls
       runs command ls in control group test1 in all mounted controllers.

       cgexec -g cpu,memory:test1 ls -l
       runs command ls -l in control group test1 in controllers cpu and memory.

       cgexec -g cpu,memory:test1 -g swap:test2 ls -l
       runs command ls -l in control group test1 in controllers cpu and memory and control group test2 in controller swap.

FILES

       /etc/cgrules.conf
       default libcgroup configuration file

SEE ALSO

       cgrules.conf (5)
