prlimit
PRLIMIT(1) User Commands PRLIMIT(1)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 lim-
its 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
Do not print a header line.
-o, --output list
Define the output columns to use. If no output arrangement is specified, then a default set is used. Use --help to get a list of
all supported columns.
-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.
