The answer from was useful but didn't work for me on Big Sur - so here's an updated version of that script. How much space are on ALL disks (sum) on this host, and how much is available on ALL disks (sum) ? I just want to use one or more CLI commands, which somehow let me respond this question:

Map auto_home 0B 0B 0B 100% 0 0 100% /homeĪgain, there are 2 lines (for /dev/disk1s1 and /dev/disk1s4) showing: Volume Total Space and Volume Free Space it seems they both lists the same thing:įilesystem Size Used Avail Capacity iused ifree %iused Mounted on So, my problem is how to correctly parse it to get:įrom the output, I can't simply sum all the lines starting with:

Read-Only Volume: Not applicable (not mounted) Volume Free Space: 0 B (0 Bytes) (exactly 0 512-Byte-Units) Volume Total Space: 0 B (0 Bytes) (exactly 0 512-Byte-Units)

Read-Only Volume: Not applicable (no file system) Volume Name: Not applicable (no file system)Ĭontent (IOContent): GUID_partition_schemeĭisk Size: 500.3 GB (500277788672 Bytes) (exactly 977105056 512-Byte-Units)

On macOS High Sierra, with SSD formatted with APFS, I've got: diskutil info -all
