I have a perl script which calls a command which before executing asks for confirmation. How do I handle this in Perl?
For example let say in my perl script I am doing the following
`ssh myServer`;
Before connecting I get a prompt asking to proceed or not. I have to provide yes as my next command. How can I achieve this? Any code snippet would be useful.
If you are looking at interactive you can use Expect on the CPAN...
"Expect is a generic tool for talking to processes that normally require
user interaction. This might be running an ftp client to grab a file,
telnetting to a router to grab statistics or reset an interface. Or, as in the
case of a place I recently administered, to start up a secure webserver without
having to be physically at the machine to enter the super secret password."
However, there are other (better) methods to automate SSH login. I.e. by using ssh-keygen
From Net::SSH :
interactive Set to a true value if you're using Net::SSH::Perl interactively. This is used in determining whether or not to display password prompts, for example. It's basically the inverse of the BatchMode parameter in ssh configuration.
Defaults to false.
