How can I write in a shell setup with a script?

I want to automate my installation of teamviewer. I can set up teamviewer using the command teamviewer setup which runs in the gnome shell and asks me for the credentials. I would like to be able to automate this in a script and not have to enter the credentials by hand.

I have already use command like:

$ printf "xxxxx\nxxxx" | teamviewer setup

But didn't work.

Any solutions ?

teamviewer setup command

My problem was solved by the tool advised by raj. Thanks to him ! This tool is "Expect". https://linux.die.net/man/1/expect

Expect is a program that "talks" to other interactive programs according to a script. Following the script, Expect knows what can be expected from a program and what the correct response should be. An interpreted language provides branching and high-level control structures to direct the dialogue. In addition, the user can take control and interact directly when desired, afterward returning control to the script.

Example: (In my case)

#!/usr/bin/expect

spawn teamviewer setup   
expect "username:"          
send "xxxxxx\r"      
expect "password:"       
send "xxxxxx\r"     
wait
