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:
