FREE (1)

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 shared memory and buffers used by the kernel. 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.
