trailing newlines

trailing newlines

[Arnold D. Robbins]

OK, here's another try, (tested, even!):

	x = '
	string

	with lots

	of


	embedded newlines

	'
	gawk '
	{
		if (! first)
			print save
		else
			first = 1
		save = $0
	}

	END	{	printf ("%s", save) }' <<< $x

Your luck with other awks may vary, particularly when processing
binary data; I have much higher confidence in gawk in that regard.

I'm not sure if I get the point, but isn't this what you want:

	x = `` ($nl) { echo $x }		# strips all newlines
or
	fn deletenl {
		* = `` ($nl) { echo $* }
		while ( ! ~ $#* 0 1 ){		# echo all args but the last
			echo $^1
			shift
		}
		echo -n `` ($nl) { echo $^1 }	# echo last arg without nl
	}
	x = `` () { deletenl $x }

To be honest, deletenl squeezes repeated nls into one.
