| ## How do I open trace in UI from command line? |
| When collecting traces from the command line, a convenient way to open traces |
| is to use the [open_trace_in_ui script](/tools/open_trace_in_ui). |
| |
| This can be used as follows: |
| ```sh |
| 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: |
| ```sh |
| tools/open_trace_in_ui -i /path/to/trace |
| ``` |
