The following script let you turn your screen brightness up/down, but also adjust the color for night time.

Copy and paste code below in a nightlight.sh file

chmod +x nightlight.sh

and run

./nightlight.sh on .5

Code:

#!/bin/sh
export DISPLAY=$(w $(id -un) | awk 'NF > 7 && $2 ~ /tty[0-9]+/ {print $3; exit}')
PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games

display=`xrandr | grep "\ connected" | cut -d" " -f1`
brightness="$2"
# Check if brightness was specified.  If not, set screen to 50% brightness
if (echo $2 | grep [0-9]);then
         brightness="$2"
elif (echo $1 | grep -q help);then
         echo "############"
else
         brightness=".5"
         echo "Brightness variable not set, setting to fallback of 50%"
fi
night_mode() {
   for disp in ${display}; do
     xrandr --output $disp --gamma $1 --brightness ${brightness}
  done }
# auto is for future development
# auto() {
# The idea behind auto is to setup something that can pull the actual sunrise/sunset times then automatically adjust the display.
# Ideally there would be an algorithm so it does it slowly over a period of time, say slightly change the color over 30 minutes.
# until the desired color limit is reached
#
# curl sunrise-sunset.com/timezone/time
# if (time > sunset && colorTemp != colorTempMin); then
# set color to current temp-1
# elif (time > sunrise && colorTemp != colorTempMax); then);
# set to full brightness and temp
# else
# unable to parse, skipping.
# fi
#}
 
help() {
echo " Help for nightmode script.

Typically on a cPanel host your access logs are kept in

/usr/local/apache/domlogs/username/incredigeek.com

Where username is your cPanel username and incredigeek.com is your website.

To view the logs you can use tail -f to follow the log.

tail -f /usr/local/apache/domlogs/username/incredigeek.com

You can also use grep to search the logs.

grep "text to search" /usr/local/apache/domlogs/username/incredigeek.com
