Re: [Nmh-workers] showing the n messages 'around' a particular message

Clever. That solves the problem I was having with pick doing this in
Bourne shell.

I believe this will work, and doesn't have the problem with gaps in
message numbers that kre's script does.

pre=$((`mhpath cur:-$n|wc -l`))
if [ $((2*$pre)) -lt $n ]; then
        post=$(($n-$pre))
else
        post=$((`mhpath next:$(($n/2))|wc -l`))
        pre=$(($n-$post))
fi
if [ $pre -gt 0 ]; then
        if [ $post -gt 0 ]; then
                scan cur:-$pre next:$post
        else
                scan cur:-$pre
else
        scan next:$post
fi

That's the basic idea, anyway, which is the same as the awk script I
posted earlier. You'll want to change it so you can choose middle numbers
other than "cur".
