Read the man page/explanation on crontab, and think about the line above:

A quick Google search (something you should try, based on your other posts), would tell you how to do this, and provide lots of examples.
runs it every hour, at the top of the hour. Again, please do some basic research...all FOUR of your user ID's make posts similar to this, that can easily be solved with a basic search. You still don't post follow ups, mark threads as solved, or even say thanks...as I've asked before, why, exactly, should we keep helping you?

As acid_kewpie said. Regarding your crontab entry, in addition you need to specify a minute at which the job should be scheduled, otherwise the asterisk will cause the execution at every minute of every hour. E.g. suppose you want to run the job at 8:00, 9:00, 10:00 and so on, the crontab entry should be:
Do you want to run at 8:23, 9:23, 10:23 an so on?
Moreover it's not necessary to specify a step equal to 1 (as in */1) since it is the default.

Sorry, but I just don't believe you. Four people making the EXACT same spelling/grammar errors? All of you posting each others names on the posts that you make sometimes?? And if you're helping your 'friends' to "posting in proper manner", perhaps you should first start doing it. How about spelling out your words, too, as you've been asked before, and tell your 'friends' to do it as well.

And if your 'team' is in the same office, why do you respond to each others posts here, rather than answering each other in person?

..and your 'team' seems to post the same questions over and over, about the same topics. Since you're all in the same office, are you not talking to each other?

Again, you rarely (if ever), post a follow up, answer questions that are asked of you, mark posts as solved, or do any basic research before posting a question.
