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)

          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 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
