Take the 2-minute tour ×  I would like to learn udev rules. Here

70-persistent-cd.rules  70-persistent-net.rules  README
victor@X301A1:~$ sudo gedit /etc/udev/rules.d/01-my-first-
udev.rules  My rule:  ACTION=="add", RUN+="echo HELLO ! >
/home/victor/udev_test_log.txt"  After saving the file:   sudo
udevadm control --reload-rules  I expected that connecting an
USB device would write in the file but nothing happen. Where am
I wrong?  share|improve this question add comment  1 Answer  In
