So that one can, for instance, use it with wc -l:
# perf list *:*write* | wc -l
60
Or to look for the "bio" tracepoints, without 'perf list' headers:
# perf list *:*bio* | head
block:block_bio_backmerge [Tracepoint event]
block:block_bio_bounce [Tracepoint event]
block:block_bio_complete [Tracepoint event]
block:block_bio_frontmerge [Tracepoint event]
block:block_bio_queue [Tracepoint event]
block:block_bio_remap [Tracepoint event]
