evemu-describe, evemu-record - print information and events from an input device


evemu-describe [/dev/input/eventX]

evemu-record [/dev/input/eventX]


evemu-describe gathers information about the input device and prints it to stdout. This
information can be parsed by evemu-device(1) to create a virtual input device with the
same properties.

evemu-record captures events from the input device and prints them to stdout. The events
can be parsed by evemu-play(1) to let a virtual input device created with evemu-device(1)
emit the exact same event sequence.

evemu-describe and evemu-record need to be able to read from the device; in most cases
this means they must be run as root.

If an event node is provided, evemu-describe and evemu-record use that event node.
Otherwise, the user must interactively choose from a list of detected devices.


If evtest-record does not see any events even though the device is being used, the device
may be grabbed by a process (EVIOCGRAB). This is usually the case when debugging a
synaptics or wacom device from within X. VT switching to a TTY or shutting down the X
server terminates this grab and the devices can be recorded. For most X drivers, disabling
the device also removes the grab.

The following command shows the processes with an open file descriptor on the device.

fuser -v /dev/input/eventX
