Cron job to remind myself to stretch

cron.md

Type crontab -l to see your cron jobs. Type crontab -e to edit them. You have to use Vim apparently.

Add a line like this:

0,30	*	*	*	*	/Users/YOURNAME/Documents/scripts/stretch.sh

That is on every 0th and 30th minute of the hour. Make sure all the separators in there are tabs!

stretch.sh

#!/bin/bash

# Nonvisual cue in a relatively non-robotic voice
say Time to stretch -v Tessa

# Buffer time to finish whatever thought
sleep 20

# Sleep the screen
pmset displaysleepnow

I'm not 100% sure, but I believe crontab -e is using whatever is set as $EDITOR for the shell session. This is usually vim, I think. If you preferred emacs, then what I've done is:

EDITOR=emacs crontab -e # or "nano", for simplicity

Some versions of Ubuntu may favor $SELECTED_EDITOR, which I believe is set by the selected-editor command (stored in ~/.selected_editor, or you could try using $VISUAL like shown here). I think the path shown would make me guess you're on MacOS though.
