h ALL=NOPASSWD: /usr/bin/brightlight -i 20 -f /sys/class/backlight/amdgpu_bl0
But doing the command still gives me a permission error.
h@pop-os:~$ brightlight -i 20 -f /sys/class/backlight/amdgpu_bl0
brightlight: could not open "brightness" file: Permission denied
Also
h@pop-os:~$ sudo -l
Matching Defaults entries for h on pop-os:
env_reset, mail_badpass, secure_path=/usr/local/sbin\:/usr/local/bin\:/usr/sbin\:/usr/bin\:/sbin\:/bin\:/snap/bin
User h may run the following commands on pop-os:
(ALL : ALL) ALL
(root) NOPASSWD: /usr/bin/brightlight -i 20 -f /sys/class/backlight/amdgpu_bl0
Things I have tried:
- Rebooting
- Creating a file in
/etc/sudoers.d/brightlight
with last line of config above
EDIT: Fixed, you need to add sudo
, and it won't prompt you for a password
Best Answer
Your entry in
/etc/sudoers
means that you can runwithout being asked for a password. It doesn't mean you can run
without
sudo
.
