[centos] Couple Of Script Questions

[FN-GM]

Hello,

 

I have a .sh script I wish to run by Cron every hour on a CentOS box.

 

1. What folder should I place the .sh file please?

2. Would this Cron config work please?

 

0 */1 * * * .folder/script.sh

 

 

Thanks

0 */1 * * * will run every one hour.

 

If you put the script in: /etc/cron.hourly/ it will do the same thing and you won't need the cron config.

 

Remember to make the script executable

 chmod u+x /etc/cron.hourly/script.sh

crontab guru is VERY useful, spent ages attempting to sort out a schedule and someone suggested i look at it.

seeing it on screen suddenly made the examples and manual make sense.

You really need to use an absolute path when referencing your script as there is no guarantee that .folder/script.sh will be on the PATH.

 

Like this:

 

0 */1 * * * /path/to/my/folder/script.sh

 

However, as CentOS already has cron.hourly already set up you might as well use that. What I generally do is keep all my scripts in a directory called /etc/scripts and then symlink them into the appropriate cron directory.

 

ln -s /etc/scripts/script.sh /etc/cron/cron.hourly/script.sh

This worked a treat! Thanks!
