plimit(1) User Commands plimit(1)NAMEplimit - get or set the resource limits of running processes
SYNOPSISplimit [-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 identified by the process-ID list, pid.
Otherwise plimit reports the resource limits of the processes identi‐
fied 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 lim‐
its. 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)
nh n hours (for CPU time only)
mm:ss minutes and seconds (for CPU time only)
The soft limit cannot exceed the hard limit.
-c soft,hard Set core file size limits (default unit is 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 kilo‐
bytes).
-t soft,hard Set CPU time limits (default unit is seconds).
-v soft,hard Set virtual memory size limits (default unit is kilo‐
bytes).
OPERANDS
The following operands are supported.
pid Process ID list.
EXIT STATUSplimit returns the exit value zero on success, non-zero on failure
(such as no such process, permission denied, or invalid option).
FILES
/proc/pid/* process information and control files
