limit

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 is also 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 .
