standard input to commands in a shell script

[Shiping Zhang]

When I invoke the following script, the process always pauses at
the password prompt. I have to hit the return key to make it
proceed. I don't know what's the problem. Do you have the same
problem if you try it? I'm working on a Sun-3 with os4.1. I appreciate
it if anyone can point out the problem for me. Thanks.
