Hello, The -q/--quiet option is to suppress headers or messages (in stdio) so that it can be copied to other place if users just want to see the numbers. This was suggested by Arnaldo.
Note that this patchset only implements it in a couple of commands. If it seems ok, it can be applied to others later. The code also is available at 'perf/quiet-v1' branch in my tree git://git.kernel.org/pub/scm/linux/kernel/git/namhyung/linux-perf.git Thanks, Namhyung Namhyung Kim (6): perf utils: Add perf_quiet_option() perf utils: Check verbose flag properly perf report: Add -q/--quiet option perf diff: Add -q/--quiet option perf annotate: Add -q/--quiet option perf record: Honor quiet option properly tools/perf/Documentation/perf-annotate.txt | 4 ++++ tools/perf/Documentation/perf-diff.txt | 4 ++++ tools/perf/Documentation/perf-report.txt | 4 ++++ tools/perf/builtin-annotate.c | 4 ++++ tools/perf/builtin-diff.c | 14 ++++++++++---- tools/perf/builtin-record.c | 3 +++ tools/perf/builtin-report.c | 21 ++++++++++++++++----- tools/perf/util/annotate.c | 2 +- tools/perf/util/debug.c | 17 +++++++++++++++++ tools/perf/util/debug.h | 1 + tools/perf/util/dso.c | 2 +- tools/perf/util/hist.c | 6 +++--- tools/perf/util/pmu.c | 8 ++++---- tools/perf/util/sort.c | 8 ++++---- tools/perf/util/symbol-elf.c | 2 +- 15 files changed, 77 insertions(+), 23 deletions(-) -- 2.11.1
