NAME

       cgget - print parameter(s) of given group(s)

SYNOPSIS

       cgget [-n] [-v] [-m] [-b] [-r <name>] [-g <controller>] [-a] <path> ...
       cgget [-n] [-v] [-m] [-b] [-r <name>] -g <controller>:<path> ...

DESCRIPTION

       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.

EXAMPLES

       $ cgget -r cpuset.cpus -r cpuset.mems first second
       first:
       cpuset.cpus=0-1
       cpuset.mems=0

       second:
       cpuset.cpus=0
       cpuset.mems=0

       $ cgget -n -r cpuset.cpus -r cpuset.mems first second
       cpuset.cpus=0-1
       cpuset.mems=0
       cpuset.cpus=0
       cpuset.mems=0

       $ cgget -nv -r cpuset.cpus -r cpuset.mems first second
       0-1
       0
       0
       0

       $ cgget -n -g cpu /
       cpu.rt_period_us=1000000
       cpu.rt_runtime_us=950000
       cpu.shares=1024

       $ cgget -m
       Unified Mode (Cgroup v2 only).
