The ROS record info automative, the log dir is random like this, it not easy to find the sequence of log dirs? So is there any way to name the log dirs by our owe?

The name of those directories is identical to the UUID that is used to identify the "session" started by the ROS Master when you start it. It is called the run_id. An example:

setting /run_id to 9a7666b8-c0b1-11e8-9b32-1866da2c09f4

After the master has shut down, you can rename the ..

.. directory to whatever you want.

While it is running though, I don't believe that would be a good idea.

I've always wonder if it was possible too. Would it be a good workaround to get the /run_id param at the beggining. Then, in a if (ros::isShuttingDown()) condition, search for the log directory according to the param to change its name ? With that it's done when the ros master isn't running.
