I'm writing a korn shell script that includes automatic secure copying of a file to several servers.  If the current user is not configured for scp on the server, it will prompt for a password.  I'd like to catch this prompt and end the scp call if the prompt occurs.  Any help would be greatly appreciated!

Hi,

For this, use expect. The links below are useful in learning expect. You may download expect from the home page if not already available on your m/c.

i.g. ssh-keygen is the way to go
If that is not possible then expect will be best.

I was able to use the resources you gave to get a basic understanding ot Tcl and Expect and wrote a small script to accomplish what I needed in less than an hour!  Thanks so much!  :-)
