Fabric - how to use an interactive shell on remote computer?

I am trying to use Fabric to run commands on a remote machine.

This works fine, until the command on the remote machine is interactive. In that case, Fabric return the interactive shell, but force me to type the info needed, while I am trying to send a command that does everything in remote, so I can automate the procedure.

Example:

from fabric.api import *
env.hosts=['myhost.mydomain']
env.user='root'
run(test1/myapp; exectask; exit)

I run a cli application on a remote machine, that uses interactive shell, so it is waiting for me to type the command (exectask); then once done, to exit, I call the exit command.

What happens now is that the app launch, Fabric show me the interactive UI and I still need to type exectask and after, exit.

How can I tell fabric to run that app, then pass the command to the interactive shell and then the exit to quit?

I see that Fabric has the prompt feature, but that's to ask the user to input data, while I want to just pass the commands and get the result back.

You might want to look into pexpect, a pure-Python module that works like expect. Essentially, it allows your program to spawn an external program or process, then control it just like a human was interacting with it. You program in what the program should expect to see (hence the name), then what action(s) to take.
