Moderator: "This is more or less an exact duplicate of the accepted answer."
Response: The "more" and "less" fixed 3 bugs that prevented the cron job spec from running on my system (a common 10.04 Ubuntu server environment).
Moderator: "I'd go and find some newer and unanswered things to provide answers to. Thanks."
Response: I'd Googled to find this question without filtering in google for page update date. The answer pointed me in the right direction, but the bugs mentioned above caused me an hour of debugging headaches--and it's not just my ignorance that caused me to flounder, cron job specs are notoriously difficult to debug and git syntax is notoriously finicky. I thought I'd save future SO users from the same headache.
Could my answer be undeleted, as it clarifies the original, accepted answer, and if not, why?
