## 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 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 (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.
