Yes maybe but why do it if the toolchain already does it?

OTOH if you do it why do it if it doesn't work?

So one must assume it works, if the programs don't work
somewhere it doesn't matter what you say or what discussion
that's always gonna be a problem.

Yes, but here it was quite a big difference and you can also
se on the command that it is actually better, if you have
measured advantage and observed/theoretical than that means
the better one is ... better!

But we can save the day and my function by finding a new use
case for it - see below...

# thanks to gmane.emacs.help
longest-line () {
    local f=$1
    awk 'length > max_length { max_length = length; longest_line = $0 } END { print longest_line }' $f
}

longest-lines () {
    local f=$1
    local lines=${2:-10}
    awk '{ print length($0) " " $0; }' $f | sort -n -r | head -n $lines
}

$ longest-lines /usr/share/dict/american-english-insane 5
