free - Display amount of free and used memory in the system
free [-b | -k | -m] [-o] [-s delay ] [-t] [-V]
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shared memory column should be ignored; it is obsolete.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 [Toc] [Back]
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. Unless
specified free subtracts/adds buffer memory from/to the used/free memory
reports (respectively!).
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.
