sftp with a user defined shell

[John Davidorff Pell]

in bash, you can check if the variable $- includes the letter i in it. 
If it does, then its interactive. If you check the man page for your 
shell, it should tell you how to determine if it is interactive. It is 
likely something similar. For example, in many shells you can check if 
the prompt variable is set ($PS1 in bash).

You can also check if stdout is a tty. If it is interactive, it almost 
certainly is, and if it is not, then it almost certainly is not. 
(though both are possible.) I just noticed that you said your shell 
requires a tty... Why?

You said your shell was "rc"? take a look at 
http://www.star.le.ac.uk/~tjg/rc/ There is also a mailing list that you 
can ask on for the specifics of your shell and how to tell if it is 
interactive.

May I ask why you have output from the shell anyway?

P.S. I've cc'd the list again. :-)
