问题
I am attempting to automate uploading some files from my Linux server to an FTP-enabled Windows server. I am successfully doing so manually using SFTP and then issuing the put command. However, when called from cron, my script keeps stopping for a password.
Below is the code I am attempting to use:
#!/usr/bin/expect
#!/bin/sh
clear
spawn sftp remoteuser@43.123.0.10
expect "password"
send "world"
expect eof
As it stands, it stops each time to request a password. Why doesn't send "world" complete the password dialog?
UPDATE:
#!/usr/bin/expect
#!/bin/sh
clear
spawn sftp remoteuser@43.123.0.10
expect "remoteuser@43.123.0.10's password:"
send "world"
expect eof
Now I get the following error:
xml_reports.sh: line 5: spawn: command not found
couldn't read file "remoteuser@43.123.0.10's password:": no such file or directory
xml_reports.sh: line 7: send: command not found
couldn't read file "eof": no such file or directory

Try like this:
#!/bin/bash
expect -c "
spawn sftp remoteuser@XX.XX.XX.XX
expect \"password\"
send \"PASSWORD\r\"
interact "

You need to use arguments when you run it. Read this article. It explains how to do this properly.

What is happening is Expect is still waiting for the pattern to arrive (until timeout), it could be that "password" is not in the prompt of sftp and that it could be "Password" or something else.
