man page for the unix linux bsd command free
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 The shared memory column should be ignored; it is obsolete.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. 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.
FILES
/proc/meminfo-- memory information
