cgexec - run the task in given control groups
cgexec [-h] [-g <controllers>:<path>] [--sticky] command [arguments]
The cgexec program executes the task command with arguments arguments in the given control
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-
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.
Display this help and exit.
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-
