What this snippet does
A tmpfs mount lives in memory and never touches disk, which suits ephemeral secrets and caches.
Expected output
tmpfs 64.0M 0 64.0M 0% /tmp
Why practise typing this
Typing volumes & storage code builds muscle memory for the symbols and indentation Docker 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.
