NAME

       pcp-free - report on free and used memory in the system

SYNOPSIS

       pcp free [-bkmgoltV] [-c count] [-s interval]

DESCRIPTION

       pcp-free  gives a summary display of the total amount of free and used physical memory and
       swap in the system, as well as the caches used by the kernel.

       When  invoked  via  the  pcp(1)  command,  the   -h/--host,   -a/--archive,   -O/--origin,
       -s/--samples,  -t/--interval,  -Z/--timezone  and  several other options become indirectly
       available.

   Options
       The -b/--bytes switch displays the amount of memory in bytes;  the  -k/--kilobytes  switch
       (set  by  default)  displays  it  in  kilobytes;  the -m/--megabytes switch displays it in
       megabytes.

       The -t/--total switch displays a line containing the totals.

       The -o switch disables the display of a "buffer adjusted" line.  If the -o option  is  not
       specified,  free  subtracts  buffer  memory  from  the used memory and adds it to the free
       memory reported.

       The -s/--interval switch activates  continuous  polling  delay  seconds  apart.   You  may
       specify  any  floating  point  number  for  delay,  or indeed any valid pmParseInterval(3)
       specification, which includes microsecond resolution delay times.  This  can  be  used  in
       conjunction with the -c/--samples option to terminate the display after count iterations.

       The -l switch shows detailed low and high memory statistics.

       The current version of pcp-free can be queried using the -V/--version option.

NOTES

       pcp-free  is  inspired  by  the  free(1)  command  and  aims to be command line and output
       compatible with it.

       The shared memory column should be ignored; it is obsolete.
