What this snippet does
file inspects content rather than the extension, so it catches mislabelled files.
Expected output
/bin/ls: ELF 64-bit LSB pie executable report.pdf: PDF document, version 1.7
Why practise typing this
Typing viewing files 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.
