What this snippet does
SSH refuses to use a private key that other users can read.
Expected output
Permissions 0644 for 'id_ed25519' are too open.
Why practise typing this
Typing ssh & remote 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.
