It basically means you don't have a tty attached (as in an interactive session). It's the "stty" commands in your .profile that are complaining. Basically it means: -

"how can i configure what keys do what if you haven't got a keyboard!!"

When seen through cron, these errors can happily be ignored. If you really don't want to see them, redirect output to /dev/null

This is the script that I think causes problem:

#!/bin/sh tty -s if [ "$?" != "0" ] then . /etc/profile fi exp FILE=/disc5/Exports/Full_Prod0.dmp GRANTS=Y CONSTRAINTS=Y FULL=Y USERID=system/passwd exit 0

And in /etc/profile I have
tty -s istty=$? [ "$istty" = "0" ] && trap "echo logout" 0 Coul you please suggest wether there is any way of rewriting this which will get rid of my error - ~

Create a resource file, separate from your profile,
that contains all your common environment variable that
your scripts need. Source *that*, and quit sourcing the profile.

Either that, or rewrite the profile so that stty command
execution is conditional on being sourced via tty.

Thank you all- I changed profile to
tty -s [ "$?" = "0" ] && stty erase '^?'
and it is okay now
Many Thanks
