Memoria RAM e SWAP del mio PC Desktop viste da Mageia

I comandi:

[~]$ free -o  # Indica memoria RAM e SWAP totale, usata, libera, share, buffer, cache
[~]$ lspci -knn | grep -iA 1 memory # visualizza i Memory Controller presenti
[~]$ dmesg|egrep -i swap          # elenca partizioni di SWAP montate
[~]$ su
Password:
[root@]> dmidecode --type memory # fornisce informazioni dettagliate sulla RAM in uso

L’output:

bash-4.3$ free -o  # Indica memoria RAM e SWAP totale, usata, libera, share, buffer, cache
             total       used       free     shared    buffers     cached
