For those that have never used crontab, it can be a daunting task to schedule a simple script. As with all things, I highly recommend that you learn the meanings of CLI programs and their usage etcetera. With that said, I wanted to check my crontab job against a generator of sorts just to be sure I had it right. If you want a simple click and go on crontab generator, I recommend using the one provided by HTML Basix. Enjoy!
