From cdd5b2d1fc86f8dda383d4f0b4ac9b533539e76a Mon Sep 17 00:00:00 2001 From: Ivan Khoronzhuk Date: Fri, 11 Oct 2019 03:27:54 +0300 Subject: samples/bpf: Fix HDR_PROBE "echo" 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.
