HI
If I compare numbers on what free -m displays or what is the number on meminfo, they are different
free -m
total used free shared buffers cached
Mem: 492 23 469 0 1 14
-/+ buffers/cache: 7 485
Swap: 0 0 0
meminfo:
total: used: free: shared: buffers: cached:
Mem: 516644864 25026560 491618304 0 1560576 15425536
Swap: 0 0 0
MemTotal: 504536 kB
MemFree: 480096 kB
MemShared: 0 kB
Buffers: 1524 kB
Cached: 15064 kB
SwapCached: 0 kB
Active: 5556 kB
Inactive: 12048 kB
HighTotal: 0 kB
HighFree: 0 kB
LowTotal: 504536 kB
LowFree: 480096 kB
SwapTotal: 0 kB
SwapFree: 0 kB
Committed_AS: 1156 kB
VmallocTotal: 491512 kB
VmallocUsed: 596 kB
VmallocChunk: 490916 kB
What if I would somehow get the number of free memory and store it somewhere. Then memtester reads the number from stored place and checks that much amount of memory that number(should be in MB) is writen in stored place. Please help
Have a nice Day
Matt

Linux Kernels 2.6.16 and up provide a way to instruct the kernel to drop the page cache, inode and dentry caches on command. This tip can help free Linux memory without a reboot.
Note: This is a non-destructive operation. Dirty objects are not freeable, hence; you must run sync beforehand.

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 used by the kernel. The
shared memory column should be ignored; it is obsolete.
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.
-c, --count count
Display the result count times. Requires the -s option.
-l, --lohi
Show detailed low and high memory statistics.
-o, --old
Display the output in old format, the only difference being this option will disable the display of the "buffer adjusted" line.
-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.
