Saturday, 17 Nov, 2012 crontab from http://ss64.com/osx/crontab.html instead of the *, you may wish to use the following shortcut strings: string meaning ------ ------- @reboot Run once, at startup. @yearly Run once a year, "0 0 1 1 *". @annually (sames as @yearly) @monthly Run once a month, "0 0 1 * *". @weekly Run once a week, "0 0 * * 0". @daily Run once a day, "0 0 * * *". @midnight (same as @daily) @hourly Run once an hour, "0 * * * *". Also, according to my experience, if you create a script named, say "do-something.sh", it simply won't work because of the .sh extension, so name your crontab scripts without the .sh extension (...and don't forget to shebang and chmod+x your scripts).
