issues in setting up cron.

Hey Guys,

Just a small query...\

I have a shell script which will backup my system & it works just fine if i run it manually. I put in below entry at the end of /etc/crontab:

01 * * * * /tmp/

It should run the script every hour?? but it just doesn't seem to be doing anything. I have checked that crond service is up and running..have also tried restarting it but still same issue.

System in use is RHEL5.

Thanks in advance.

I didn't want to wait for another hour so i changed it to:

*/10 * * * * root /tmp/

& it worked. Have changed it back to:

01 * * * * root /tmp/

& i hope it will work. lets wait and watch...

Thanks a lot guys!

Cron while exceute the script will look for the binaries in the PATH variable /usr/bin:/bin. But if you run the script manually it will look for the actual PATH variable which may contains the binaries you are executing in the script.

Try sourcing the resource configuration files that are sourced during login at the top of your script. Typically .bashrc and .bash_profile

Best Regards
