Question

There is an interactive shell console, I can get into it, run specific set of commands inside the console and exit from it.

Now I want to write a bash script that connects to an interactive shell console and runs my commands silently, exits at the end without any interaction. This means I want to have everything automated in a non-interactive way. Any ideas how can I achieve this?

I am trying something like, say, blabla shell is the interactive console here, it always bring me to the interactive mode 🙁

/usr/bin/blabla shell << EOF 
do A,
do B,
do C
quit
EOF

I have a long/specific version of this question can be found here ->

Closing stdin should do the trick:

exec <&-
