8.6.2 M�moire libre

free et top donnent de bonnes informations sur les ressources m�moire. Ne vous inqui�tez pas de la taille de "used" sur la ligne "Mem:", lisez plut�t la ligne en-dessous (38792 dans l'exemple ci-dessous).

     $ free -k # for 256MB machine
                  total       used       free     shared    buffers cached
     Mem:        257136     230456      26680      45736     116136 75528
     -/+ buffers/cache:      38792     218344
     Swap:       264996          0     264996

La quantit� exacte de m�moire physique peut �tre confirm�e par grep '^Memory' /var/log/dmesg, qui dans notre cas d'exemple donne � Memory: 256984k/262144k available (1652k kernel code, 412k reserved, 2944k data, 152k init) �.

     Total         = 262144k = 256M (1k=1024, 1M=1024k)
     Free to dmesg = 256984k = Total - kernel - reserved - data - init
     Free to shell = 257136k = Total - kernel - reserved - data

Environ 5Mo ne sont pas utilisables par le syst�me parce que le noyau les utilise.
