Cron Jobs not working

Hello,

I have a script that works manually, but not when setup in crontab. Any ideas? let me know if you need more info thanks.

Since cron has a limited path, try to use the whole path to the commands and files in the script.

Kind regards

This is my cron entry:

Code:

2 1 * * * root /usr/local/bin/myscript.sh > /var/log/myscript.log 2>&1

Its the direct path to the script.

Use the absolute path to commands and files in the script itself.

Kind regards

Im sorry im still a bit green. What would an example be? thanks

Edit myscript.sh
If you have a command, lets say

Code:

ls /home

use
[CODE]/bin/ls /home
Or set the path at the beginning of the script

Code:

PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin

Kind regards

Ok so I execute

Code:

[root@myserver-1 bin]# whereis myscript.sh
myscript: /usr/local/bin/myscript.sh

So wouldn't /usr/local/bin/myscript.sh be the absolute path?

You need to set the absolute path from the commands and files IN the script

Kind regards

still not working. It has to be something simple, it seems like everything is telling me that usr/local/bin/myscript.sh is the absolute path. Im not sure how to get to the command absolute paths.

Add this at the top of the script

Code:

PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin

Or post the contents of your script

Kind regards

Here is one that I am testing:

Code:

#!/bin/bash
echo Hello World

repo · 12-29-2011, 05:13 PM

Try

Code:

#!/bin/bash
/bin/echo Hello World > /var/log/myscript.log

Then look in

Code:

/var/log/myscript.log

Kind regards

ice2921 · 12-29-2011, 05:17 PM

It works I get:

Code:

[root@myserver-1 bin]# cat /var/log/myscript.log
Hello World
[root@myserver-1 bin]#

You added what to what?
Try

Code:

2 1 * * * /usr/local/bin/myscript.sh

no need for root
If there are any problems, cron will sent a mail to root.

Kind regards
