CGEXEC(1) libcgroup Manual CGEXEC(1)
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. con-
trollers 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 tem-
plate 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 ser-
vice 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 mem-
ory.
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.
