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 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 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)

       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 kilobytes).

       -t soft,hard    Set CPU time limits (default unit is seconds).

       -v soft,hard    Set virtual memory size limits (default unit is kilobytes).

OPERANDS
       The following operands are supported.

       pid	Process ID list.

EXIT STATUS
       plimit 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
