LED Keyboard does not light up.... Help?

Question

I have a keyboard which has LED Lights under it. When i power my computer up it will light up when accessing the BIOS, but once it gets to the Grub screen it turns off, and im not exactly sure how to enable the light, my BIOS setting is set to ALWAYS have it on, but that is not working and im trying to find out how and can enable and disable it upon command if possible.
Ive googled and havent found anything on this, do you guys know what to do with this?

Definitely follow this advice. Makes life much easier. As for the code itself, first be aware that you can't just "sh" it. It runs using arguments, so you'd run something like
# ./enlighten increase keyboard
Though I wrote that script for zsh, I believe it should be compatible with bash without issue. Below is a much simpler version of the script which will only increase or decrease the keyboard backlights:
#!/bin/bash
#<- Configuration ->
kbd=/sys/class/leds/toshiba::illumination/brightness
kstep=15
self="$(basename $0)"
#<- Error Handling ->
E_HELP=44
E_PERMS=45
#<- Function Declarations ->
permissions () {
if [ "$UID" != 0 ]; then
echo "$self must be run with root privileges"
exit "$E_PERMS"
fi
usage () {
echo "Usage: $self [-h|--help] <increase|decrease>"
exit "$E_HELP"
update-kbd () {
permissions
sudo tee "$kbd" <<< "$new"
exit 0
#<- Run Contents ->
case "$1" in
-h|--help)
usage
increase)
current="$(<"$kbd")"
new="$(( current + kstep ))"
update-kbd
decrease)
current="$(<"$kbd")"
new="$(( current - kstep ))"
update-kbd
usage
esac
Assuming you have the correct file being pointed to, you should be able to just run (assuming you keep it named "enlighten")
# ./enlighten increase
Let me know how that works for you.
All the best,

Ok so i copied that script, and tried to run "./enlighten increase" but it said i needed to be sudo, so i did it with sudo, and it said "sudo: ./enlighten: command not found"
Then i just did 'sh enlighten increase" And this time it gave me:
enlighten: line 29: `update-kbd': not a valid identifier
I have no idea what that would mean.
When i google "`update-kbd': not a valid identifier" all it comes up with is my topic lmfao. Not much help there.
