Execute a batch file every hour

[dam034]

Dear users,

I created a batch file. I want to execute it every hour as root user.

The batch file is in /srv/cmd/, I created a symbolic link in /etc/cron.hourly but it doesn't work.

How can I fix?

Thanks

Do you mean a bash script? I haven't heard the term batch file in quite a long time.

Hi dam034.

I would start checking the permissions. Could you run these commands and post back the results? (You can copy/paste the text. Please use CODE tags)

ls -l /srv/cmd/your_script

ls -ls /etc/cron.hourly/link_to_your_script
Then I would double check (1) you have the proper shebang, (2) that the commands you are executing are in the PATH (which is usually not the same that the default you use for regular users), and finally (3) revise if you have interactive content that won't work on a cron script.

The easiest way to help you would be to post the script.

Regards.

These are the commands:


root@ubrouter:/srv/cmd# ls -l
totale 8
-rwxrwx--- 1 dam034 apgr 445 feb 12 18:36 aggiornamento.sh
-rwxrwx--- 1 dam034 apgr 320 feb 13 00:54 registro.log


root@ubrouter:/etc/cron.hourly# ls -l
totale 0
lrwxrwxrwx 1 root root 33 feb 12 18:35 ddns.sh -> /srv/cmd/aggiornamento.sh
As you can see, I want to execute the command as root user.


What is the matter?

Thanks

Filenames (and I assume this applies to symlinks as well) in the /etc/cron.houly, /etc/cron.daily etc. directories have some particular requirements. Form the DEBIAN SPECIFIC section of `man cron`:



As described above, the files under these directories have to be pass
some sanity checks including the following: be executable, be owned by
root, not be writable by group or other and, if symlinks, point to
files owned by root. Additionally, the file names must conform to the
filename requirements of run-parts: they must be entirely made up of
letters, digits and can only contain the special signs underscores
('_') and hyphens ('-'). Any file that does not conform to these
requirements will not be executed by run-parts. For example, any file
containing dots will be ignored.
