NAME

6       free - Display amount of free and used memory in the system
7

SYNOPSIS

9       free [-b | -k | -m] [-o] [-s delay ] [-t] [-V]
10

DESCRIPTION

12       free  displays the total amount of free and used physical and swap mem‐
13       ory in the system, as well as the buffers  used  by  the  kernel.   The
14       shared memory column should be ignored; it is obsolete.
15
16   Options
17       The  -b  switch  displays  the amount of memory in bytes; the -k switch
18       (set by default) displays it in kilobytes; the -m switch displays it in
19       megabytes.
20
21       The -t switch displays a line containing the totals.
22
23       The -o switch disables the display of a "buffer adjusted" line.  If the
24       -o option is not specified, free subtracts buffer memory from the  used
25       memory and adds it to the free memory reported.
26
27       The -s switch activates continuous polling delay seconds apart. You may
28       actually specify any floating point number for delay, usleep(3) is used
29       for microsecond resolution delay times.
30
31       The -V displays version information.
