crontab -e

Will open the crontab file for the current user, here you can add 
commands that are to executed at certain times. The crontab will look 
something like:

# m h  dom mon dow   command
0 0 * * * /foo/bar

where the command /foo/bar will be executed every day (dom, mon and dow 
are a *, meaning 'for all') at 12 pm.
