[Solved] Problems with permissions for a script

Question

Hi I realize the topic "permissions in Linux" is something that you can find very easily in the internet but I cant seem to figure out a solution for my problem.
I currently have a working script (taken from the ArchWiki) which enables me to change my display brightness. However I must be either superuser or root to be able to use it since it sends commands to the necessary devices.
I am currently using fluxbox as "desktop environment" and I want to be able as normal user to change the brightness without calling "sudo" everytime. I have also bound the necessary keys in the fluxbox/keys file to send the necessary commands to the script so my only problem is now with the permission.
Every help is much appreciated

Answer 1

ok it works that way (at least when I execute the additional script which contains the sudo command).
for some reason fluxbox doesnt react when I press the keycode that I looked up with xev (although it works with a combination like "Mod4 b: exec ~/script")
anyway I think I'll stick with that solution and add some additional commands in the script (like toggle wlan on/off), thx for the quick help
edit: ok now I'm having difficulties with extending the script
I want to add additional paramters so the script can be used multifunctional depending on the parameter you launch it with.
however he seems to think that the String which I want to compare with the parameter is a command.
here's the code
#! /bin/sh
if [$1 = "brightness"]; then
if [$2 = "up"]; then
//call the actual brightness script with sudo
elif [$2 = "down"]; then
// call the actual brightness scrip with sudo
else
echo "invalid parameters!"
exit 1
fi
fi
exit 0
I execute the script like this
~/script brightness up
but he only returns me
~/script: line 2: [brightness: command not found
so whats wrong with the code?
