This time I’m bringing you a self-documented cron table file (with an example), that is, a tidy cheatsheet diagram embedded as comments that does just one thing, helps you remember the crontab syntax:

# * * * * * command to be executed
# - - - - -
# | | | | |
# | | | | +—– day of week (0 - 6) (Sunday=0)
# | | | +——- month (1 - 12)
# | | +——— day of month (1 - 31)
# | +———– hour (0 - 23)
# +————- min (0 - 59)

# Alarm clock set to 6:30AM
30 6 * * * /home/nano/alarm

I hope you find it useful, thanks for reading and happy May Revolution Day to everyone!
