[Israel.pm] web-based script

Shlomo,

This can all be done from the shell.
And as much as I like to write Perl -- I'd rather use already-written tools.

>  	[in the browser]
>  	* goto url x.y.z
>  	* login (username+password) [1]

This can be done with wget and/or lwp-request and/or curl.

>  	<new page>
>  	* select a radio button
>  	* select another radio button
>  	* hit submit

Can you emulate this by hacking the URL?
Otherwise you can use WWW::Mechanize (which means you will write code, but
it's easy).

Of course, this is basic.

Rsync runs over SSH, and can be used with SSH keys.
That means you can sync the directory, run scripts, chmod, etc.
I wrote a backup script for my former company that backs things up over
SSH using rsync and also chmods stuff.

Let me know if my way of thinking is correct :)
