PROGRAM:
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 values 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.
GENERAL OPTIONS
-h, --help
Display help text and exit.
--noheadings

-o, --output list
Define the output columns to use. If no output arrangement is specified, then a

-p, --pid
Specify the process id; if none is given, the running process will be used.
--raw Use the raw output format.
--verbose
Verbose mode.
-V, --version
Display version information and exit.

EXAMPLES
prlimit --pid 13134
Display limit values for all current resources.
prlimit --pid 13134 --rss --nofile=1024:4095
Display the limits of the RSS, and set the soft and hard limits for the number of
open files to 1024 and 4095, respectively.
prlimit --pid 13134 --nproc=512:
Modify only the soft limit for the number of processes.
prlimit --pid $$ --nproc=unlimited
Set for the current process both the soft and ceiling values for the number of
processes to unlimited.
prlimit --cpu=10 sort -u hugefile
