Run Cron Every Hour Debian

Question

How can i setup a cron job in debian to run a certain url once every hour. There`s no control panel or anything.,

thanks

Answer 1

You can do that in different ways:

• Make a simple script to run the command and copy it to /etc/cron.hourly (don't forget to add the execute permission on it).
• Add a snippet of crontab to /etc/cron.d.
• Use crontab -e as root and add a line to it executing the command directly.

To access an URL you can use links, lynx, wget, curl and other text mode browsers. Each one will have it's quirks. I suppose curl or wget can be the easier ones to use.

I strongly recommend you to read this article as well as the cron manpage.

Answer 2

Edit /etc/crontab and add a line like the following:

0 * * * * * root /path/to/executable

Or you can put it in your user crontab by running crontab -e and add the same line but omit the username field.

Of course, as others have said, you can add a script or symlink to /etc/cron.hourly.

Answer 3

Command scheduling with cron. Take a look at /etc/cron.hourly. Everything you place in there will get executed each and every hour.

Answer 4

You should be able to find the answer here, though the above comments lay it out nicely already. http://www.debianhelp.co.uk/schedulejobs.htm

Answer 5

There's a useful script shipped with nagios which just loads a single web page.

• Install the nagios-plugins-basic package

• then put something like this in /etc/cron.hourly

  #!/bin/sh
  /usr/lib/nagios/plugins/check_http -H serverfault.com -u /questions/246048/ > /dev/null
