Usually, we set "stty erase ^h" in the login shell to enable the backspace key. This is good during interactive sesssion.
For some shell script that enclose complicated SQL sessions, this might cause some errors like "stty: Inappropriate ioctl for device"
So, the question is how to avoid executing the "stty erase ^h" command by testing if the current shell is interactive or not. If it's interactive, use stty. Otherwise, skip it.
Somebody suggests add the following in the .cshrc
# Interactive commands go here
stty erase ^h
I did. But this does NOT work. It always gives me an error message ": no match" when I log in. That means stty is ALWAYS skipped. This is not what I expected. Any suggestion? Thank you!
