[Expectperl-discuss] FAQ Suggestion

[ivo w. <ivo...@br...>]

Dear Roland:

Thanks a lot for taking care of this module.  It seems incredibly
useful, so I am now trying to learn it. Alas, not easy to figure out.

One of the most common uses of Expect is probably use of "ssh" under
linux with a password that sits in my program.  So, I am trying to
figure out from the docs what the recommended way to do this is.
Therefore, I think this could be a good candidate for an example.  It is
probably obvious to the initiated, but not so to those of us that don't
even know the TCL Expect command.

The logic of executing ssh would seem to suggest that I need to look
for:

"Are you sure you want to continue connecting (yes/no)?"
	to which I would answer "yes".  This prompt may or may
	not appear.

"Password: "
	to which I would give my password.  This may or may not
	appear the first time.

"Password: "
	a second time, which would lead me to die the program (I had the wrong
password).

EOF
	which should make me return happily.


It is not at all obvious to me how I would write a function
	run_sshcommand( $remotecommand, $remotepassword )
that automates this.  From the docs, it is not easy to see if multiple
arguments to expect are sequential, or alternatives. Also, some
statements suggest I need "-re", other examples seem to suggest that I
can use qr//;

Any help would be appreciated.
