From 66f5a0779af2a4f28b1832f6c20bc9d3b1ab1886 Mon Sep 17 00:00:00 2001 From: Ravi Bangoria Date: Tue, 17 Apr 2018 09:43:44 +0530 Subject: [PATCH] perf tools: Add '\n' at the end of parse-options error messages Few error messages does not have '\n' at the end and thus next prompt gets printed in the same line. Ex, linux~$ perf buildid-cache -verbose --add ./a.out Error: did you mean `--verbose` (with two dashes ?)linux~$ Fix it.
