   3 #Each line describes a limit for a user in the form:
   4 #
   5 #<domain>        <type>  <item>  <value>
   6 #
   7 #Where:
   8 #<domain> can be:
   9 #        - an user name
  10 #        - a group name, with @group syntax
  11 #        - the wildcard *, for default entry
  12 #        - the wildcard %, can be also used with %group syntax,
  13 #                 for maxlogin limit
  14 #        - NOTE: group and wildcard limits are not applied to root.
  15 #          To apply a limit to the root user, <domain> must be
  16 #          the literal username root.
  17 #
  18 #<type> can have the two values:
  19 #        - "soft" for enforcing the soft limits
  20 #        - "hard" for enforcing hard limits
  21 #
  22 #<item> can be one of the following:
  23 #        - core - limits the core file size (KB)
  24 #        - data - max data size (KB)
  25 #        - fsize - maximum filesize (KB)
  26 #        - memlock - max locked-in-memory address space (KB)
  27 #        - nofile - max number of open files
  28 #        - rss - max resident set size (KB)
  29 #        - stack - max stack size (KB)
  30 #        - cpu - max CPU time (MIN)
  31 #        - nproc - max number of processes
  32 #        - as - address space limit (KB)
  33 #        - maxlogins - max number of logins for this user
  34 #        - maxsyslogins - max number of logins on the system
  35 #        - priority - the priority to run user process with
  36 #        - locks - max number of file locks the user can hold
  37 #        - sigpending - max number of pending signals
  38 #        - msgqueue - max memory used by POSIX message queues (bytes)
  39 #        - nice - max nice priority allowed to raise to values: [-20, 19]
  40 #        - rtprio - max realtime priority
  41 #        - chroot - change root to directory (Debian-specific)
