i find crontab confusing too - and i am not alone.

i am sure you have done your research but you can have look at this website:

and consider installing something like webmin:

if you find these admin tasks too confusing.

Hi S@R@H, your post leaves a lot to be asked. For instance, what should the script accomplish? Assuming that your script, which is to be run by cron is comprehensive, my approach would be:

1. To have everything in a script including the output redirection to file
2. Alternatively, rather than cd to directory containing script, use the full path e.g. /home/oracle/sh/rman.sh >> /u01/rman.log

I think the major caveat is that you do not have command seperation. Maybe introducing a colon or preferably '&&' between the directory /home/oracle/sh and you script may help. It will also be great if you try your scripts on the commandline before adding them to cron.

You can have only one active definition of a var eg SHELL, in the file. If you have more, the last/latest will be the one that takes effect.
