Generally meaning you add your user to the wheel group, e.g. as root # gpasswd -a andre wheel (some distros have dropped wheel group and instead use a 'sudo' group) Then as root, visudo to edit the sudoers file and set: ## Uncomment to allow members of group wheel to execute any command # %wheel ALL=(ALL) ALL ## Same thing without a password %wheel ALL=(ALL) NOPASSWD: ALL (generally toward the bottom of the file) That will allow you to set /sys/class/backlight/intel_backlight/brightness with the call in the script, e.g. with the line sudo sh -c "echo '"$newbl"' > '"$blfn"'"
