^. is the 1st char, put into () (protected with \) to store in \1
which gets uppercased with \U.
Julien wanted monday -> Mon, it seems. That's what the cut does: take
three bytes. We can loose the cut, too:
echo monday | sed 's/\(^.\)\(..\).*/\u\1\L\2/'
which matches 2 more characters and lowercases those with \L
