Command-Line Scripting

Hello,

I'm looking for advice on automating a bash script with the purpose of: sending a txt file routinely, every day. I'm currently running a command-line only shell of Ubuntu 14.04, and am relatively new to linux in general.

I have used the following command

# alpine (side-carrot) /home/sample.txt

but this command opens up Alpine, and requires ctrl-X to send (in addition to entering the password). I was able to remove the confirmation que in the Alpine config settings. How can I bypass the ctrl-X input, and have my password be entered automatically, as part of the bash script?

Thank you!
