Re: Help with "A specified file does not support the ioctl system call." in cron

I've experimented the "stty: tcgetattr: A specified file does not
support the ioctl system call." problem...

At last, I've discovered it was because we had at /etc/profile al
line like:

stty erase ^?

dropping out this line solved the problem. As far as I can explain this
line was failing because my script (this one being called by cron)
performed a "su - " call. So this su tried to execute user environment
(sourcing profile files) and stty failed because it was not being
called from a tty.

You can check /etc/profile and user's ~.profile for a stty command.

Hope this helps,

Serxio Barral.
