What is the difference between “gksudo nautilus” and “sudo nautilus”?
I have tiny script that I want it to run on start-up, but it needs sudo privileges so I use gksudo for the job. but it fails. (it works correctly using sudo.) Is there any difference between sudo and gksudo beside the inteface?
BTW: this is the tiny script I mentioned:
#!/bin/bash
cat /sys/devices/platform/sony-laptop/kbd_backlight|if read state; then \
echo $((1-$state)) | sudo tee /sys/devices/platform/sony-laptop/kbd_backlight; fi;
