passwords in shell scripts
 

hello!

i'm trying to write a script that will run a bunch of tests for me by transferring files using SCP.

I would like to write a script that will SCP, then enter my password and repeat. How do i write a code that wil wait for a prompt and then enter a password? Thanks a lot!

Edit: sorry, that puts it in automatically, and you want to put it in manually.

Well, now I don't know if this is what you have in mind or not. :(

Here's part of an ftp script using expect.

#!/usr/bin/expect -f

spawn ftp -i 192.168.0.1
expect "Name"
send "fred\r"
expect "Passsword:"
send "mypassword\r"

thanks "homey" haha...

i'll try it out...

is "expect" a command you can use for any program when waiting for a prompt?..i guess so?

You would be better off using keys for your authentication. Read up on how to generate keys for SSH and ssh-agent.

expect is the answer. If u havent done this b4, then better experiment with auto-expect which generates an expect script based on ur terminal activity.

1) run auto-expect.
2) do some activity. (ex: telnet to a machine and login and do an ls or somerthing)
3) exit (exits from auto-expect)
4) ls -ltr, last file is ur except script. run it
