Synopsis

                     limit [-h] [resource [limit]]

Display limits or set a limit on resources used by the current process and by each process it creates. If no limit is given, the current limit is printed for resource. If resource also is omitted, all limits are printed. By default, the current limits are shown or set; with -h, hard limits are used. A hard limit imposes an absolute limit that can’t be exceeded. Only a privileged user may raise it. See also unlimit.

Option

-h

Use hard, not current, limits.
