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 memory 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ignored; it is obsolete.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, (3)
is used for microsecond resolution delay times.
The -V displays version information.
