NAME
free - Display amount of free and used memory in the system
SYNOPSIS
free [-b | -k | -m] [-o] [-s delay ] [-t] [-V]
DESCRIPTION
free displays the total amount of free and used physical and swap mem-
ory in the system, as well as the buffers used by the kernel. The
shared memory column should be ignored; it is obsolete.
Options
The -b switch displays the amount of memory in bytes; the -k switch
(set by default) displays it in kilobytes; the -m switch displays it in
megabytes.
The -t 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 switch activates continuous polling delay seconds apart. You may
actually specify any floating point number for delay, usleep(3) is used
for microsecond resolution delay times.
The -V displays version information.
