cgconfigparser
CGCONFIGPARSER(8) libcgroup Manual CGCONFIGPARSER(8)
NAME
cgconfigparser - setup control group file system
SYNOPSIS
cgconfigparser [-h] [-l <filename>] [-L <directory>] [...]
OPTIONS
-h, --help
Displays help.
-l, --load=FILE
Parses the control groups configuration file Sets up the control group file system defined by the configuration file and mounts
mount points defined by the configuration file. The format of the file is described in cgconfig.conf. This option can be used mul-
tiple times and can be mixed with -L option.
-L, --load-directory=DIR
Finds all files in given directory and parses them in alphabetical order like they were specified by -l option. This option can be
used multiple times and can be mixed with -l option.
-a <agid>:<auid>
defines the default owner of the rest of the defined control group's files. These users are allowed to set subsystem parameters and
create subgroups. The default value is the same as has the parent cgroup.
-d, --dperm=mode
sets the default permissions of a control groups directory. The permissions needs to be specified as octal numbers e.g. -d 775.
-f, --fperm=mode
sets the default permissions of the control group files. The permissions needs to be specified as octal numbers e.g. -f 775. The
value is not used as given because the current owner's permissions are used as an umask (so 777 will set group and others permis-
sions to the owners permissions).
-s, --tperm=mode
sets the default permissions of the control group tasks files. The permissions needs to be specified as octal numbers e.g. -f 775.
The value is not used as given because the current owner's permissions are used as an umask (so 777 will set group and others per-
missions to the owners permissions).
-t <tuid>:<tgid>
defines the default owner of tasks file of the defined control group. I.e. this user and members of this group have write access to
the file.
ENVIRONMENT VARIABLES
CGROUP_LOGLEVEL
controls verbosity of the tool. Allowed values are DEBUG, INFO, WARNING or ERROR.
