Re: Calling interactive programs from with a script

Hi,
First, look here for formatting your post.
Second, this is really a unix question, not a perl one, since this is the way passwd works.
Please look at Expect for some clues how to solve your problem.

Yours,

Second, this is really a unix question, not a perl one, since this is the way passwd works. I disagree. He's not having problems with passwd per se, he's having problems accessing it through perl. There is a difference. As for the original question, I think that part of the problem can have some light shed on it by the answer to the question "where do stdout and stderr go when you do a system call?" . Also, passwd expects a tty to be communicating with it, and has provisions to prevent things like scripts interfacing with it. Fortunately for you, Expect.pm is around. Expect simulates a tty, allowing you to script an interface to things like passwd. thor	[reply]
