PROGRAM:

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.
