understanding free -m output

vincix · 04-02-2018, 04:27 AM

I don't understand how come shared memory is bigger than total memory. Is this normal? Or is it a bug?

Code:

 free -m
              total        used        free      shared  buff/cache   available
Mem:           2048        1817         230        2910           0         230
Swap:          2048         748        1299

Hi:

I ran the free -m cmd on my system to see and my shared is smaller than total memory-

Code:

free -m
              total        used        free      shared  buff/cache   available
Mem:           3940        1275        1937          38         727        2248
Swap:          2047           0        2047
bash-4.3$

Not sure if it's a bug or not.
