My First Crontab




Ok, it's not the first crontab I've ever written. This is my crontab template that I just created for mysellf because even though I've been using cron since the late 80s, I still keep forgetting which side is minutes. How sad is that?!?

I copied the nice format from Wikipedia's cron page.

The first line (the only line that isn't a comment, and therefore an actual crontab entry) is my initial test to make sure cron is working for the account.

   * * * * *  echo hi >/tmp/a.hi
#  * * * * *  command to execute
