User Commands plimit(1)
NAME
plimit - get or set the resource limits of running processes
SYNOPSIS
plimit [-km] pid...
plimit {-cdfnstv} soft,hard... pid...
DESCRIPTION
If one or more of the cdfnstv options is specified, plimit
sets the soft (current) limit and/or the hard (maximum)
limit of the indicated resource(s) in the processes identi-
fied by the process-ID list, pid. Otherwise plimit reports
the resource limits of the processes identified by the
process-ID list, pid.
Only the owner of a process or the super-user is permitted
either to get or to set the resource limits of a process.
Only the super-user can increase the hard limit.
OPTIONS
The following options are supported:
-k On output, show file sizes in kilobytes (1024
bytes) rather than in 512-byte blocks.
-m On output, show file and memory sizes in megabytes
(1024*1024 bytes).
The remainder of the options are used to change specified
resource limits. They each accept an argument of the form:
soft,hard
where soft specifies the soft (current) limit and hard
specifies the hard (maximum) limit. If the hard limit is not
specified, the comma may be omitted. If the soft limit is an
empty string, only the hard limit is set. Each limit is
either the literal string unlimited, or a number, with an
optional scaling factor, as follows:
nk n kilobytes
nm n megabytes (minutes for CPU time)

512-byte blocks).
-d soft,hard Set data segment (heap) size limits (default
unit is kilobytes).
-f soft,hard Set file size limits (default unit is 512-
byte blocks).
-n soft,hard Set file descriptor limits (no default
unit).
-s soft,hard Set stack segment size limits (default unit
is kilobytes).
-t soft,hard Set CPU time limits (default unit is
seconds).
-v soft,hard Set virtual memory size limits (default unit
is kilobytes).
