UNIX cron has been around for over 30 years. It’s a way to schedule events. Here’s what it looks like:
# .—————- minute (0 – 59)
# | .————- hour (0 – 23)
# | | .———- day of month (1 – 31)
# | | | .——- month (1 – 12) OR jan,feb,mar,apr …
# | | | | .—- day of week (0 – 6) (Sunday=0 or 7) OR sun,mon,tue,wed,thu,fri,sat
# | | | | |
# * * * * * command to be executed
Here is a question:
Can you add time to a schedule, i.e. say “5 hours after the cron fires do something”, in cron syntax?
Hints:
a) Can you express the first day of the month?
b) Can you express the last day of the month?
