Bash - Send commands to a CLI

I am writing a script in bash (on Linux) and I need to send some commands to a command line interface but I don't know how to do it.

To open the CLI :

myserver# ovirt-shell [options]

Then I'm in a new shell where I execute some commands to get back informations :

[oVirt shell (connected)]# list hosts > hosts.txt<br>
[oVirt shell (connected)]# list vms > vms.txt

So I would like to execute ovirt-shell and send my commands (list vms/hosts) directly in my script, in "silent-mode".

How can I do this ?

Since the program reads from stdin, you can pipe the commands to stdin:

ovirt-shell <<EOF
list hosts
list vms
EOF

An alternative is to store the commands in file and execute it like this:

ovirt-shell -f filename
