NAME

7       cgexec - run the task in given control groups

SYNOPSIS

11       cgexec [-h] [-g <controllers>:<path>] [--sticky] command [arguments]
12
13

DESCRIPTION

15       The  cgexec  program executes the task command with arguments arguments
16       in the given control groups.
17
18
19       -g <controllers>:<path>
20              defines the control groups in which the task will be run.   con‐
21              trollers  is a list of controllers and path is the relative path
22              to control groups in the given controllers list.
23
24              This flag can be used multiple times to define multiple pairs of
25              lists of controllers and relative paths.  Instead of the list of
26              all mounted controllers, the wildcard b"*b" can be used.
27
28              If this option is not used, cgexec will automatically place  the
29              task in the right cgroup based on /etc/cgrules.conf.
30
31              If  /etc/cgrules.conf  configuration  file is used, there can be
32              used template names. Then the control group name contains a tem‐
33              plate  in  destination  tag  (see  cgrules.conf  (5)) and if the
34              cgroup does not exist in execution time, it is created, based on
35              /etc/cgconfig.conf specification.  If the specifications are not
36              present the group is created with the default kernel values.

38
39       -h, --help
40              Display this help and exit.
41
42
43       --sticky
44              If running the task command with this option, the daemon of ser‐
45              vice  cgred  (cgrulesengd process) does not change both the task
46              of the command and the child tasks.  Without  this  option,  the
47              daemon  does  not  change the task of the command but it changes
48              the child tasks to the right cgroup based  on  /etc/cgrules.conf
49              automatically.

EXAMPLES

53       cgexec -g *:test1 ls
54       runs command ls in control group test1 in all mounted controllers.
55
56       cgexec -g cpu,memory:test1 ls -l
57       runs  command  ls -l in control group test1 in controllers cpu and mem‐
58       ory.
59
60       cgexec -g cpu,memory:test1 -g swap:test2 ls -l
61       runs command ls -l in control group test1 in controllers cpu and memory
62       and control group test2 in controller swap.
