Strange behaviour of cron

[Kalin Evtimov]

Hi!
I am really confused with a problem that I have now. I have a perl script, that opens a file and writes something in there. I run the script as user oracle from the command line and everything works fine. But when I do the same command from cron, for the same user, I get error message "Permission denied" when it tries to open the file to write. I tried changing permissions and so on, but no change, works from command line, does not work from cron. What is wrong here?

Thank you!

Kalin,
who is the cronjob running as?
If it is the oracle user, please remember that cron does not use the login file, so your environment is going to be different.
Please ensure you specify all variable you need within your script. For example $ORACLE_HOME would not be know, unless specified within the script. So you may write to $ORACLE_HOME/test but that translates into /test !

Thank you, Peter, you were on the right way. When I changed the path to the file to absolute path, it worked properly.
