Short indeed,
but yet another trick.
Informatics is not about learning an encyclopedia of tricks
if you want to drive on the highway instead of doing rally driving.
lines=$(wc -l -- "${files[@]}" | awk '{print $1}')
doesn't carry its meaning.
This is a loss of brain time.
You can learn tricks and win the Mathematics Olympiad,
and still be clueless about Riemann Hypothesis.
