Subject: [PATCH RFC bpf-next 06/10] samples: bpf: makefile: fix HDR_PROBE
Date: Fri, 30 Aug 2019 03:50:33 +0300 [thread overview]
Message-ID: <20190830005037.24004-7-ivan.khoronzhuk@linaro.org> (raw)
In-Reply-To: <20190830005037.24004-1-ivan.khoronzhuk@linaro.org>
echo should be replace on echo -e to handle \n correctly, but instead,
replace it on printf as some systems can't handle echo -e.
