NAME
       prlimit - get and set process resource limits

SYNOPSIS
       prlimit [options] [--resource[=limits] [--pid PID]

       prlimit [options] [--resource[=limits] command [argument...]

DESCRIPTION
       Given a process ID and one or more resources, prlimit tries to retrieve
       and/or modify the limits.

       When command is given, prlimit will run this  command  with  the	 given
       arguments.

       The  limits parameter is composed of a soft and a hard value, separated
       by a colon (:), in order to modify the existing values.	If  no	limits
       are given, prlimit will display the current values.  If one of the val‐
       ues is not given, then the existing one will be used.  To  specify  the
       unlimited  or  infinity	limit  (RLIM_INFINITY),	 the -1 or 'unlimited'
       string can be passed.

       Because of the nature of limits, the soft limit must be lower or	 equal
       to  the	high  limit  (also  called the ceiling).  To see all available
       resource limits, refer to the RESOURCE OPTIONS section.

       soft:hard    Specify both limits.

       soft:	    Specify only the soft limit.

       :hard	    Specify only the hard limit.

       value	    Specify both limits to the same value.
