[SOLVED] The "free" command

Hello All,

I issued the free command and I was wondering if someone can explain to me what shared, buffers and cache mean. I have 8GB of RAM and I can see that I only have 523M free while I have 5.3G cached. See below:

Code:

$ free -h
             total       used       free     shared    buffers     cached
Mem:          7.8G       7.3G       523M        23M       100M       5.3G
-/+ buffers/cache:       1.9G       5.9G
Swap:           0B         0B         0B

Not sure if this is ok.

Regards,
