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 The shared memory column should be ignored; it is obsolete.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.
