FREE(1) Linux User's Manual FREE(1)NAMEfree - Display amount of free and used memory in the system
SYNOPSISfree [-b | -k | -m] [-o] [-s delay ] [-t] [-V]
DESCRIPTIONfree 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shared memory column should be ignored; it is obsolete.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.
