[-r <name>] [-g <controller>]
[-a] <path> ...
cgget [-n] [-v] [-m] [-b] [-r
<name>] -g <controller>:<path>
...
Prints the parameter(s) of input cgroup(s). If neither controller
nor variable are specified, the values of all possible variables are
displayed.
- <path>
- is the name of the cgroup which should be read. This parameter can be used
multiple times.
- -a, --all
- print the variables for all controllers which consist in the given cgroup
- -b
- ignores the default systemd delegated hierarchy path and constructs the
path of the control groups relative to the cgroup root hierarchy.
- -c
- displays the controllers and their versions. This option can be used along
with -m option.
- -g
<controller>
- defines controllers whose values should be displayed. This option can be
used multiple times.
- -g
<controller>:<path>
- defines control groups whose values should be displayed. This option can
be used multiple times.
- -h, --help
- display help and exit
- -m
- displays the current control groups setup mode. The control groups can be
set up in one of three modes, legacy (cgroup v1 only), unified (cgroup v2
only) or hybrid (cgroup v1/v2).
- -n
- do not print headers, i.e. names of groups.
- -r, --variable
<name>
- defines parameter to display. This option can be used multiple times.
- -v, --values-only
- print only values, not parameter names.
