NAME


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

SYNOPSIS


free [options]

DESCRIPTION


free displays the total amount of free and used physical and swap memory in the system, as
well as the buffers and caches used by the kernel. The information is gathered by parsing
/proc/meminfo. The displayed columns are:

total Total installed memory (MemTotal and SwapTotal in /proc/meminfo)

used Used memory (calculated as total - free - buffers - cache)

free Unused memory (MemFree and SwapFree in /proc/meminfo)

shared Memory used (mostly) by tmpfs (Shmem in /proc/meminfo, available on kernels 2.6.32,
displayed as zero if not available)

buffers
Memory used by kernel buffers (Buffers in /proc/meminfo)

cache Memory used by the page cache and slabs (Cached and Slab in /proc/meminfo)

buff/cache
Sum of buffers and cache

available
Estimation of how much memory is available for starting new applications, without
swapping. Unlike the data provided by the cache or free fields, this field takes
into account page cache and also that not all reclaimable memory slabs will be
reclaimed due to items being in use (MemAvailable in /proc/meminfo, available on
kernels 3.14, emulated on kernels 2.6.27+, otherwise the same as free)

OPTIONS


-b, --bytes
Display the amount of memory in bytes.

-k, --kilo
Display the amount of memory in kilobytes. This is the default.

-m, --mega
Display the amount of memory in megabytes.

-g, --giga
Display the amount of memory in gigabytes.

--tera Display the amount of memory in terabytes.

-h, --human
Show all output fields automatically scaled to shortest three digit unit and
display the units of print out. Following units are used.

B = bytes
K = kilos
M = megas
G = gigas
T = teras

If unit is missing, and you have petabyte of RAM or swap, the number is in
terabytes and columns might not be aligned with header.

-w, --wide
Switch to the wide mode. The wide mode produces lines longer than 80 characters. In
this mode buffers and cache are reported in two separate columns.

-c, --count count
Display the result count times. Requires the -s option.

-l, --lohi
Show detailed low and high memory statistics.

-s, --seconds seconds
Continuously display the result delay seconds apart. You may actually specify any
floating point number for delay, usleep(3) is used for microsecond resolution delay
times.

--si Use power of 1000 not 1024.

-t, --total
Display a line showing the column totals.

--help Print help.

-V, --version
Display version information.
