Bash / Shell Script: correct / debug Shell script to wake up screen at 7am, launch Chromium, and sleep screen at 7pm

Hi, I have a few Shell scripts, I want to run automatically on a Raspberry Pi, Here is how it goes: 1. The Crontab part should launch the [login to view URL] script and schedule [login to view URL] at 7am, and [login to view URL] at 7pm 2. [login to view URL] should launch [login to view URL] if a reboot happens between 7am and 7pm; BUT if the reboot happens 7pm and 7am (the opposite),... then it should run [login to view URL] 3. [login to view URL] should wake up screen, launch chromium-browser... launch [login to view URL] script, etc. See below 4. [login to view URL] (see below) WHAT TO DO: this is not working and I have no time to debug / correct, if you can do it, please let me know. Please also test it on your side, if it works then your job is done.
