Blob Blame History Raw
From 5899f2f5163de4d68fbb35831e1f2230c22c71b3 Mon Sep 17 00:00:00 2001
From: Mike Gilbert <floppym@gentoo.org>
Date: Tue, 14 Jul 2015 22:22:14 -0400
Subject: [PATCH] Replace echo -n with printf in code with a /bin/sh shebang

POSIX does not mandate that echo support the -n parameter.
printf has more well-defined behavior.
