It is a simple command to show the device logs. It comes with various options so that we can easily filter out the logs which we are interested in.
Right-click in the logcat messages window, choose select all. Then your save will be all logcat messages in that window (including the ones scrolled out of view).
Simply hit Ctrl+C to exit the adb logcat.
In log messages, verbose has the lowest priority and silent has the highest priority.
