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.

              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 created, based on /etc/cgconfig.conf specification.   If  the  specifica-
              tions 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 (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.
