NAME
       cgsnapshot - generate the configuration file for given controllers


SYNOPSIS
       cgsnapshot  [-h]  [-s]  [-t] [-b file] [-w file] [-f outputfile] [con‐
       troller] [...]


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  cgcon‐
       fig.conf configuration file.


       -b file
              Display only variables from the blacklist.  The default location
              of the blacklist is /etc/cgsnapshotblacklist.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 outputfile



       -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  vari‐
              able is not blacklisted, the whitelist is checked.  If the vari‐
              able 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.
