Make automatic screenshots

1) in Automator create an app called and save it in /Applications/AutoScreenshot.app. The app contains the following shell script:

vardate=$(date +%Y\-%m\-%d); 
vartime=$(date +%H.%M.%S);
FOLDER=/Users/rick/Screenshots/Screenshot-auto/$vardate
mkdir -p $FOLDER
screencapture -t jpg -x "$FOLDER/Screenshot-auto $vardate at $vartime.jpg"

2) create the file ~/Library/LaunchAgents/nl.companje.screenshots.plist with the following contents:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">

3) Install and run the launchd process

# launchctl unload nl.companje.screenshots.plist
cd ~/Library/LaunchAgents/
launchctl load nl.companje.screenshots.plist
launchctl start nl.companje.screenshots
# tail /var/log/system.log
