> **TLDR:** Move running tasks to `cgroups`.
>
- Move the process with a specific PID to the control [g]roup student in the CPU hierarchy:
  `cgclassify -g {{cpu:student}} {{1234}}`
- Move the process with a specific PID to control groups based on the `/etc/cgrules.conf` configuration file:
  `cgclassify {{1234}}`
- Move the process with a specific PID to the control [g]roup student in the CPU hierarchy. Note: The daemon of the service `cgred` does not change `cgroups` of the specific PID and its children (based on `/etc/cgrules.conf`):
  `cgclassify --sticky -g {{cpu:/student}} {{1234}}`

## NAME
       cgclassify - move running task(s) to given cgroups


## SYNOPSIS
       **cgclassify** [**-g** <_controllers>:<path_>] [--sticky | --cancel-sticky] <_pidlist_>


## DESCRIPTION
       this  command moves processes defined by the list of processes (**pidlist**) to the given control
       groups.

       The pids in the pidlist are separated by spaces


### -g <controllers>:<path>
              defines the control groups where the task will be moved.  **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 *****
              can be used.

              If this option is not used then **cgclassify** will automatically move the task to a  con‐
              trol group based on **/etc/cgrules.conf**.


### --sticky
              If  this  option  is  used, the daemon of service cgred (cgrulesengd process) does not
              change both the specified **pidlist** and their children tasks.  Without this option,  the
              daemon  does not change the specified **pidlist** but it automatically changes their child
              tasks to the right cgroup based on **/etc/cgrules.conf**.


### --cancel-sticky
              If this option is used, the daemon of service cgred (cgrulesengd process) can automat‐
              ically  change  both  the  specified **pidlist** and their child tasks to the right cgroup
              based on **/etc/cgrules.conf**.


## ENVIRONMENT VARIABLES
       **CGROUP**___**LOGLEVEL**
              controls verbosity of the tool. Allowed values are **DEBUG**, **INFO**, **WARNING** or **ERROR**.


## FILES
### /etc/cgrules.conf
              default libcgroup configuration file

### /etc/cgrules.d
              default libcgroup configuration files directory


## EXAMPLES
### cgclassify -g cpu:student 1234
              moves process with pid number 1234 to control group student in cpu hierarchy.


### cgclassify 1234
              moves process with pid number 1234 to control groups based on  **/etc/cgrules.conf**  con‐
              figuration file.


### cgclassify --sticky -g cpu:/student 1234
              moves  process  with  pid  number 1234 to control group student in cpu hierarchy.  The
              daemon of service cgred does not change cgroups of pid 1234 and its children (based on
              **/etc/cgrules.conf**).
