SYNOPSIScgexec [-h] [-g <controllers>:<path>] [--sticky] command [arguments]
DESCRIPTIONThe 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.
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

cgexec -g cpu,memory:test1 ls -lruns command ls -l in control group test1 in controllers cpu and memory.
cgexec -g cpu,memory:test1 -g swap:test2 ls -lruns command ls -l in control group test1 in controllers cpu and memory and control group test2 in controller swap.
