CGEXEC(1)                      libcgroup Manual                      CGEXEC(1)



NAME
       cgexec - run the task in given control groups


SYNOPSIS
       cgexec [-h] [-g :] [sticky] command [arguments]


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


       -g :
              defines the control groups in which the task will be run.   con‐
              trollers  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.

              If  /etc/cgrules.conf  configuration  file is used, there can be
              used template names. Then the control group name contains a tem‐
              plate  in  destination  tag  (see  cgrules.conf  (5)) and if the
              cgroup does not exist in execution time, it is created, 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 ser‐
              vice  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 mem‐
       ory.

       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.
