OpenSolaris 2009.06 - man page for plimit (opensolaris section 1)

plimit(1)				  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  identified
       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  unlim-
       ited, 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
