When collecting traces from the command line, a convenient way to open traces is to use the open_trace_in_ui script.
This can be used as follows:
curl -OL https://github.com/google/perfetto/raw/master/tools/open_trace_in_ui chmod +x open_trace_in_ui ./open_trace_in_ui -i /path/to/trace
If you already have a Perfetto checkout, the first steps can be skipped. From the Perfetto root, run:
tools/open_trace_in_ui -i /path/to/trace
