I am using NSTask and NSPipe to wrap a unix command in a GUI. I've
followed most of the standard examples that use pipes to handle stdin,
stdout, and stderr and they make sense to me. But how do I deal with
interaction after the task is launched? For example, let's say I'm
trying to wrap something like scp that can't be passed a password from
the command line. How can I direct the password prompt to the GUI and
send it back to the task? Should I parse the NSData coming up the pipe
and look for the substring "password", or is there a slicker way to do
this?
Unless someone has written a Cocoa "Expect.framework" that I don't know
about, this is probably the only good solution.
Come to think of it, I suppose you could use /usr/bin/expect to handle
some of the fine points of doing this. But that might just make things
more complex. Still, "man expect" might be worth a look for you.
