sudo usermod -a -G dialout $USER

For anyone who likes knowing what they're running before they run it: usermod - modify a user account -a - add the user to supplementary groups -G - a list of supplementary groups (man page says to use -a only with -G) dialout - group that controls access to serial ports (and other hardware too) $USER - Bash variable containing current username (not a builtin, usually automatically set env variable)

uucp tty sudo usermod -a -G dialout $USER
