From 5e17b28f1e246b98e08cb463f7d72cff6415fc53 Mon Sep 17 00:00:00 2001 From: Masami Hiramatsu Date: Mon, 27 Oct 2014 16:31:31 -0400 Subject: perf probe: Add --quiet option to suppress output result message Add --quiet(-q) option to suppress output result message for --add, and --del options (Note that --lines/funcs/vars are not affected). This option is useful if you run the perf probe inside your scripts.
