Why practise typing this
Typing permissions & ownership 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.
