Crontab syntax

Personal note about crontab syntax, from left to right:

Field     Function
1o.     Minute
2o.     Hour
3o.     Month Day
4o.     Month
5o.     Week day
6o.     Command to execute


Minute     0-59
Hour     0-23
Month day     1-31
Month     1-12
Week day     0-6 (where “0″ means Sunday), 1 means Monday, etc

Sometimes I forget it, so I’m documenting it to myself. Hopefully somebody else will find it useful too. 🙂
