Even everyday tasks like importing photos and videos from cameras, or downloading movies and TV shows from iTunes can result in massive data storage. Unfortunately it is quite easy to fill your hard drive.

Additionally, even though OS X manages file fragmentation for conventional hard drives well by keeping 20MB chunks of data in contiguous blocks, this feature requires free space to work, and may suffer if you are limited on space. While nothing stops you from adding files to your drive until it can hold no more, once you start encroaching on the last ~10GB-20GB of space, the system will not be able to manage its virtual memory footprint as easily, resulting in slower performance. This command is useful to see the APFS volumes, all of which share the same free space on the containing /dev/disk1 virtual disk: $ diskutil list virtualĠ: APFS Container Scheme - +500.0 GB disk1ġ: APFS Volume Macintosh HD 15.3 GB disk1s1Ģ: APFS Snapshot .update-. 15.3 GB disk1s1s1ģ: APFS Volume Macintosh HD - Data 48.7 GB disk1s2Ĥ: APFS Volume Preboot 591.0 MB disk1s3ĥ: APFS Volume Recovery 622.When using your Mac, maintaining a small amount of free drive space is required to keep your system running optimally. Printf "Size: %.1f GB Free: %.1f GB\n", total_size_gb, total_avail_gb Total_size_gb = size_byte / 1000000000 # convert bytes to GB Size_byte = $2 * 512 # convert from 512 byte blocks # This works for a single internal disk that contains root FS

# Only use macOS versions of df, awk, etc It works for a single internal SSD, but would need changes for external disks to check each one separately. 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: I know somehow this behavior is related to APFS thing but again, I need some logic to filter out the duplicated entry. 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
