NAME

6       pcp-free - report on free and used memory in the system
7

SYNOPSIS

9       pcp free [-bkmgoltV] [-c count] [-s interval]
10

DESCRIPTION

12       pcp-free  gives  a summary display of the total amount of free and used
13       physical memory and swap in the system, as well as the caches  used  by
14       the kernel.
15
16       When  invoked  via  the  pcp(1)  command,  the -h/--host, -a/--archive,
17       -O/--origin, -s/--samples,  -t/--interval,  -Z/--timezone  and  several
18       other options become indirectly available.
19
20   Options
21       The  -b/--bytes  switch  displays  the  amount  of memory in bytes; the
22       -k/--kilobytes switch (set by default) displays it  in  kilobytes;  the
23       -m/--megabytes switch displays it in megabytes.
24
25       The -t/--total switch displays a line containing the totals.
26
27       The -o switch disables the display of a "buffer adjusted" line.  If the
28       -o option is not specified, free subtracts buffer memory from the  used
29       memory and adds it to the free memory reported.
30
31       The  -s/--interval  switch  activates  continuous polling delay seconds
32       apart.  You may specify any floating point number for delay, or  indeed
33       any  valid pmParseInterval(3) specification, which includes microsecond
34       resolution delay times.  This can  be  used  in  conjunction  with  the
35       -c/--samples option to terminate the display after count iterations.
36
37       The -l switch shows detailed low and high memory statistics.
38
39       The  current  version of pcp-free can be queried using the -V/--version
40       option.

NOTES

43       pcp-free is inspired by the free(1) command and aims to be command line
44       and output compatible with it.
45
46       The shared memory column should be ignored; it is obsolete.
