A script I run via cron that prompts me to sleep at night

go-to-sleep.sh

#!/usr/bin/env bash -x

# TO USE:
# 1. MAKE A CONFIG FILE AT ~/.go-to-bed
# it should look like this (don't include hashes in file, this will nag you starting at 12:16 AM until 6:00 AM)
# START_TIME:0.16
# END_TIME:6.0
# HUSHED_UNTIL:2023-11-23T1:40:00
#
# 2. SAVE THIS SCRIPT SOMEWHERE, maybe ~/bin/go-to-bed
# 3. ADD TO YOUR CRONTAB, mine looks like this:
# % crontab -l
# * * * * * /Users/nroyalty/bin/go-to-bed.sh -from-cron 2>/dev/null 1>/dev/null
#
# 4. TO SNOOZE, EDIT HUSHED_UNTIL AND IT WON'T NAG YOU TILL AFTER THAT TIME
# 5. TO WIN, NEVER EDIT THE FILE TO SCROLL TWITTER

if [ "$1" = "-from-cron" ]
then
    if ps aux | grep osascript | grep -q 'Time to Sleep'
    then
        echo There is probably a pending window, exiting
        exit 0
    fi
fi

alert_title="Time to Sleep"
alert_message=$(
cat <<'EOF'
Most of the time when you are using your computer at this hour you aren't doing anything worthwhile.

If you're programming or doing something else cool, edit ~/.go-to-bed to hush this message until tomorrow.

Otherwise you should consider sleeping or doing something more fun! Read a book or a new yorker article. Play a game. Play your piano.

@wongjustin99 thanks!! that seems better although I'm so used to the old behavior idk if I can switch!!

Got inspired by this one and made a Hammerspoon version: https://gist.github.com/SilverEzhik/f4626851965fa7a1be0b27bfb49280d1
