cron execute problems

Hi All,

I am running Centos 4.4 and I am having problems getting cron to run my script. I have made a script (usbback.sh) that is as follows:

#! /bin/sh
\cp -fR /data /media/usbback/
exit 0

The script runs just fine from the command line. If I make the following entry using crontab -e:

30 * * * * /root/scripts/usbback.sh

It will not run. The permissions on usbback.sh is 744. Any ideas why it won't run? Thanks.

Hi,

The first line should be #!/bin/sh (there should be no space between #! and /bin...).

Why is there a backslash before the cp command (\cp -fR....)?

Hope this helps.

I had a similar problem trying to run a cron script. I set the execute time to 12:00 and then set my KDE time to 11:59:50. Then I waited for my script to execute but id didn't.

The problem was that setting the KDE clock only sets KDE time, not system time. You need date to set it (and root privileges).
