How to send commands to other utilities in bash?

Question

bash

For example, I'm running something that provides its own interface, such as mysql . can i run create database command in bash script?
mysql cited as an example, we are talking about a utility that does not accept any startup parameters

Answer 1

Depends on the utility. If it can process standard input, just send commands to it via a pipe or from a file:
echo "create database" | utility
utility < create_database_script.txt
If it requires a terminal and interactivity, learn expect.
