I've been looking for a way to do this for a while, there are several
StackOverflow questions on the topic but so far I have not found a way to
do this.
I've written a very primitive fish function to do it *sometimes* ;)
function opt
> echo $argv | read -l command option
> man $command | grep -n -F -e $option | read -l first rest
> set number (echo $first | grep -o -E '[0-9]*')
> man $command | sed -n $number,(math $number + 20)p
> end
Anyway, very interested if anyone knows a decent way to do this.
Best,
Jon
