I trying to emulate a keyboard from golang. a lib that do this require to do the following:

sudo groupadd uinput
sudo usermod -a -G uinput my_username
sudo udevadm control --reload-rules
echo "SUBSYSTEM==\"misc\", KERNEL==\"uinput\", GROUP=\"uinput\", MODE=\"0660\"" | sudo tee /etc/udev/rules.d/uinput.rules
echo uinput | sudo tee /etc/modules-load.d/uinput.conf

what are the implications of do this ? any way to do it directly or without sudo or permissions changes, what I need to read. ?

there is any utility to use with bash on fedora. ?

This looks sensible to me. Only user in the uinput group can access the device.
Once this is done you will not need sudo to access the device.

A utility to do what? emulate a keyboard?

Added input-method, kernel, libinput, udev-rules

to send keyboard events. I don’t need a keyboard. I only need a way to send keyboard events.

And that is a priv’ed operation, I assume, which is why you have built the software you indicated and need to setup permissions as you showed.
