I'd have done it within a single script but there's always four ways to do something in bash, and if it works, it works

!. Very true... im new to language and scripting... im just proud this is not a cut and paste job :). I'm sure I could merge it all into one script.. but i like breaking it down.

I was working on a project that required me to have a display show video content based on the time of day and day of the month. It also had to have some volume control depending on what time of the morning it was. The platform was a RPi3. The schedule is as follows:

• Sun-Friday AM - Play AM playlist between 6AM and 8PM
  
  
  • Mute AM playlist between hours of 6AM and 10AM
• Sat AM - Play AM playlist between 6AM and 9PM
• Sun-Friday PM - Play PM playlist between 8PM and 6AM
• Sat PM - Play PM playlist between 9PM and 6AM

First I created my scripts. I needed to automatically initiate the playback when the system reboots (should it ever need to be rebooted). So in "/storage/.config/" i created "autostart.sh" with the following:

#!/bin/sh
(
sleep 10;
touch /storage/.config/autostarted
sh /storage/.config/startPlay.sh
) &

This starts before kodi launches and has this format so it doesn't hang.

Then I created my startPlay.sh (/storage/.config/startPlay.sh):

#!/bin/bash
#script by substancev


currday=$(date +%u)
currtime=$(date +%H%M%S)
satamstart=060000
satamfinish=210000
otherdaystart=060000
otherdayfinish=200000
muteStart=060000
muteFinish=100000


if [[ $currday -eq 6 ]]; then
  if [[ $currtime -ge $satamstart && $currtime -le $satamfinish ]]; then
    /storage/.config/playAM.sh
  else
    /storage/.config/playPM.sh
  fi
elif [[ $currday -eq 7 ]]; then
  if [[ $currtime -ge $otherdaystart && $currtime -le $otherdayfinish ]]; then
    /storage/.config/playAM.sh
  else
    /storage/.config/playPM.sh
  fi
elif [[ $currday -lt 6 ]]; then
  if [[ $currtime -ge $otherdaystart && $currtime -le $otherdayfinish ]]; then
    /storage/.config/playAM.sh
      if [[ $currtime -ge $muteStart && $currtime -le $muteFinish ]]; then
        /storage/.config/mute.sh
      else
        /storage/.config/unmute.sh
      fi
  else
    /storage/.config/playPM.sh
  fi
fi

This will handle the schedule on reboot.

Next I created my playAM.sh:

#!/bin/bash


kodi-send --host=localhost --port=9777 --action="PlayMedia(/storage/.kodi/userdata/playlists/video/AM.m3u)"
sleep 2
kodi-send --host=localhost --port=9777 --action="PlayerControl(RepeatAll)"

and playPM.sh:

#!/bin/bash


kodi-send --host=localhost --port=9777 --action="PlayMedia(/storage/.kodi/userdata/playlists/video/PM.m3u)"
sleep 2
kodi-send --host=localhost --port=9777 --action="PlayerControl(RepeatAll)"

mute.sh:

#!/bin/bash
kodi-send --host=localhost --port=9777 --action="SetVolume(0)"

unmute.sh:

#!/bin/bash
kodi-send --host=localhost --port=9777 --action="SetVolume(100)"

Then i configured my crontabs using crontab -e at the console.

crontab:

#Play AM Weekday
 0 6 * * * /storage/.config/playAM.sh
#Play PM Sun-Fri
 0 20 * * 0,1,2,3,4,5 /storage/.config/playPM.sh
#Play PM Sat
 0 21 * * 6 /storage/.config/playPM.sh
#Mute AM
 0 6 * * 1,2,3,4,5 /storage/.config/mute.sh
#Unmute AM
 0 10 * * 1,2,3,4,5 /storage/.config/unmute.sh

I'm not sure if it was necessary or not to chmod +x these scripts... so I did it anyway.

And there we have it... Kodi auto plays on the schedule I want it to be on.

Please let me know if you would have done this differently.
