Cron info

Hi,

My knowledge as far as cron is as follows:

In the user account you would like to run a command or script type in

crontab -e
This will take you into the cron file editor.

The cronjob is setup as follows

30 12 * * * echo "This job will execute now" /*Or whatever your command would be*/

30 - Minute
12 - Hour of the day
* - month day (could be set from 1-30)
* - month (could be set from 1-12)
* - day of week (0-6, where 0=Sunday)

Try the echo command in the user account you are in to echo a message to a file in the directory somewhere.

It should execute the specific time you gave it. Once you figure this out it should be pretty easy to run cronjobs from there.

Here is an example

23 17 22 8 4 echo "Is this working!" > tmp/example.txt

Make sure there is a tmp directory in your working directory.

All you need to do is change the time in crontab with the time you want the command to execute.

Hope this is of help!

Cheers
Smilie

perlo i would highly suggest that you get a unix for beginners book at your local book store.


I think the book will be much more valuable then these forums if you are completly new and looking for ALL of the answers.


I would suggest anything by Oreilly will be good to go.

If you installed Perl correctly, then you should:

1 Find the path the file "perl" was installed to - probably /usr/bin or /usr/local/bin

2 Place #!/usr/bin/perl or #!/usr/local/bin/perl - whichever matches the path you found "perl" in - at the very top of your script

3 Change the mode of your script so it's executable: chmod +777 filename.pl

But probably the best suggestion is Optimus_P's...
