how to send password to Cygwin command?

[sean]

All,

I'm trying to write a java program to execute some cygwin rsync calls
using Runtime.getRuntime().exec etc. How do I send a password to the
process that I'm running? Sending via the usual streams doesn't seem
to work.

Thanks,
Sean

It is typical that such tool open the terminal device directly, instead
of using stdin/stdout, so you can't provide the password that way.
However rsync allows you to provide the password in at least two other
ways.

man rsync

tells you more.

Alternatively, you could use rsync over ssh with public key
authentication, so you are not asked for a password.
