Can I use a Shell Script to do SFTP/SSH to Automate File Uploads

General

I’ve made some progress based on the Interactive Shell project under /Example Projects/Advanced/Shell/. I can now upload or download individual files or folders by issuing a shell command like:

scp ~/Desktop/filename remoteaccount@serveraddress:/path/filename

which uploads a file from my desktop after I’m prompted for my account password.

  1. But I’m wondering if this can be further streamlined to automatically enter the password, since third-party FTP software somehow does it without my having to do it each time.

  2. Also, is there a limit to how big a file or how many files in a folder can be transferred this way before problems (like timeouts or whatever) are likely to occur?
