Hi,

Scp (ssh) does not allow for, or have an option to give the password.

You might want to have a look at password-less scp/ssh: Shortest passwordless ssh tutorial, ever or feed your search-engine with ssh password less for other tutorials.

Hope this helps.

There are two other options you can also look at. First one is doing a pty/fork/exec of the scp command, this allows you to capture it's output and send it the password when it asks for it. Second would be to link against the libssh2 library and use it's functions to do the authentication and scp transfer.

In C for the first option you'd want to look at forkpty function.

I was reading about somethying called "expect" this morning which also works for this function? Not sure if it still is used/secure (well obviously its not secure, as its storing your password in a unencrypted form).

yep expect would work fine and I think quite a few of the scripting languages have an expect module
