Ho solo un SSD da 512 GB.
Quindi, il mio problema è come analizzare correttamente per ottenere:
- Spazio totale
- Spazio disponibile
Dall'output, non posso sommare semplicemente tutte le righe che iniziano con:
Volume Total Space
e Volume Free Space
; sembra che entrambi elencino la stessa cosa:
Volume Total Space: 500.0 GB (499963170816 Bytes) (exactly 976490568 512-Byte-Units)
Provando df -H, l'output è:
df -H
Filesystem Size Used Avail Capacity iused ifree %iused Mounted on
/dev/disk1s1 500G 309G 189G 63% 2397390 9223372036852378417 0% /
devfs 195k 195k 0B 100% 658 0 100% /dev
/dev/disk1s4 500G 1.1G 189G 1% 3 9223372036854775804 0% /private/var/vm
map -hosts 0B 0B 0B 100% 0 0 100% /net
map auto_home 0B 0B 0B 100% 0 0 100% /home
Ancora una volta, ci sono 2 linee (per / dev / disk1s1 e / dev / disk1s4) che mostrano:
Size 500G
e Avail 189G
So che in qualche modo questo comportamento è legato alla cosa di APFS; ma ancora, ho bisogno di un po 'di logica per filtrare la voce duplicata .
Voglio solo usare uno o più comandi CLI, che in qualche modo mi permettono di rispondere a questa domanda:
Quanto spazio c'è su TUTTI i dischi (somma) su questo host e quanto è disponibile su TUTTI i dischi (somma)?
