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 con‐
              trollers list.

              This flag can be used multiple times to define multiple  pairs  of  lists  of  con‐
              trollers  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.

              If  /etc/cgrules.conf configuration file is used, there can be used template names.
              Then  the  control  group  name  contains  a  template  in  destination  tag   (see
              cgrules.conf  (5))  and  if the cgroup does not exist in execution time, it is cre‐
              ated, based on /etc/cgconfig.conf specification.  If  the  specifications  are  not
              present the group is created with the default kernel values.


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


       --sticky
              If  running the task command with this option, the daemon of service cgred (cgrule‐
              sengd 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  automati‐
              cally.


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.
