What this snippet does
-f adds the filesystem type, label and UUID for each device.
Expected output
sda └─sda1 ext4 root 3f2a-1c9d / /dev/sda1: UUID="3f2a-1c9d" TYPE="ext4"
Why practise typing this
Typing disk & filesystem code builds muscle memory for the symbols and indentation Linux uses most, which prose-based typing tests never cover. DevType measures your words per minute and accuracy on this snippet and tracks the individual characters you mistype, so later lessons can target them.
