I am running some shell scripts through a foll cron job, the script works fine and there are no errors in the log file but I receive the following error in mail for the jobs:
stty: no such device or address

What does the above error indicate, here is the cron job:
0 22 * * 0 /ora_install/orainventory/admin/prod1/scripts/bkpl.sh>/home
cle/logs/bkpl.log

I am running my profile in the shell script.

Would including spaces make a difference? And does the directory /homecle/logs/ exist?

I believe that it's because you are sourcing your .profile... Check to see if your .profile has any references to stty in it (many do, such as "stty erase ^?"). If so, that's your problem; since it's being run by a process that does not have an interactive sessions, and therefore no real controlling terminal.

You can put your PATH and other important vars in the script, or make a "clean" profile that all of your cron scripts can source.

Hope this solves it.
