       cgsnapshot - generate the configuration file for given controllers

SYNOPSIS

       cgsnapshot [-h] [-s] [-t] [-b file] [-w file] [-f output_file]  [controller] [...]

DESCRIPTION

       cgsnapshot  generates  the  cgconfig  compatible  configuration  file  for  the given controllers.  If no
       controller is set, then cgsnapshot shows all mounted hierarchies.  The output is in the  same  format  as
       the cgconfig.conf configuration file.

       -b file
              Display   only   variables  from  the  blacklist.   The  default  location  of  the  blacklist  is
              /etc/cgsnapshot_blacklist.conf.  This list contains all variables which should be ignored  by  the
              cgsnapshot  If the variable is blacklisted, it will not be displayed.  If it is not present on the
              blacklist, the whitelist is checked.

       -h, --help
              display this help and exit

       -f, --file
              Redirect the output to output_file

       -s, --silent
              Ignore all warnings

       -t, --strict
              Do not display the variables which are not on the whitelist

       -w file
              Set the blacklist configuration file.  This list contains all variables which should be  displayed
              by cgsnapshot If the variable is not blacklisted, the whitelist is checked.  If the variable is on
              the whitelist, it is displayed by cgsnapshot If the variable is not on the whitelist, the variable
              is displayed and a warning message is produced.  By default the whitelist is not used.

              The warning message can be omitted using the -s, --silent flag.  If the -t, --strict flag is used,
              the variable which is not on the whitelist is not displayed.

       controller
              defines the controller whose hierarchies will be output
