Subject: [PATCH v3 bpf-next 01/14] samples: bpf: makefile: fix HDR_PROBE "echo"
Date: Mon, 16 Sep 2019 13:54:20 +0300 [thread overview]
Message-ID: <20190916105433.11404-2-ivan.khoronzhuk@linaro.org> (raw)
In-Reply-To: <20190916105433.11404-1-ivan.khoronzhuk@linaro.org>
echo should be replaced with echo -e to handle '\n' correctly, but
instead, replace it with printf as some systems can't handle echo -e.
