making a command run once every hour

I have an indexer for sphinx, and i want it to run once every hour in linux. How would i do this?


Since everyone else is posting short answers, I thought I'd be a little more descriptive...

cron is a daemon found on most *nix systems that runs scheduled commands at the specified intervals.

You add a script to the list by copying it to the folder of your choice:

  • cron.daily
  • cron.hourly
  • cron.monthly
  • cron.weekly

These folders are typically found under /etc folder.


Just to be different -

depending on your needs you could use the watch command.

  watch --interval=3600 command

cron.


Use crontab.
