Bash File Backup via SSH

Question

I am trying to make a bash script that will transfer a file from my machine to a server maintained by my school that is used to back up code. It is a hassle to transfer the file manually every single time that I want to make the transfer.

Some applications, like TextWrangler, have the ability to save to server. However, I would rather be able to do it quickly from terminal.

Where would I go from here? Would I need to somehow pass in the file I'd like to send as a parameter? Is there a way to make sure that it goes to the correct directory?

#!/bin/bash
# This should log me into orca

sftp username@place
expect "username@place password: "
sleep 1
send "mypassword"

Perhaps this question would get better answers on serverfault or ubuntu. — James Anderson

Why not use "scp" secure copy instead of sftp.

You don't need "expect" to run this, and, if you configure the remote/local certificates properly you will not need to mess with passwords.

See some examples of how simple it can be. And the full how to docs.

'scp' is probably sufficient for what you currently want. Should your scenario get more complex I'd recommend to have a look at 'rsync' (which can use ssh), see samba.org/ftp/rsync/rsync.html.
