Summary: `free' command doesn't show amount of cached memory
Product: Busybox
Version: 1.16.x
Platform: Other
OS/Version: Linux
Status: NEW
Severity: minor
Priority: P5
Component: Other
AssignedTo: unassigned at busybox.net
ReportedBy: generatorglukoff at gmail.com
CC: busybox-cvs at busybox.net
Estimated Hours: 0.0
Typical busybox `free' command output is:
# free
total used free shared buffers
Mem: 13480 8944 4536 0 968
Swap: 0 0 0
Total: 13480 8944 4536
#
which says that almost 2/3 of RAM is used. However:
# cat /proc/meminfo | grep Cached
Cached: 4272 kB
SwapCached: 0 kB
#
so in fact there is 4Mb in cache, and that means there is 9Mb usable memory
(free+cached+buffers). And this means it's only 1/3 of RAM is used. That's
confusing.
It would be nice to see amount of cached memory as well as standard line '-/+
buffers/cache:'.
