Shell Programming and Scripting

Hello.

Looking for a method of modularizing my bash script, I am stuck with such a problem. For example, I have:

MODULE_NAME="test"
FUNCTION_NAME="run"

How do I can a function with name test_run?

Something like this:

MODULE_NAME="test"
FUNCTION_NAME="run"

eval ${MODULE_NAME}_${FUNCTION_NAME}

Here is one way. I have not put test_run is a separate file but that is probably what you want to do and then source that file
so that test_run is available in your script.

#!/usr/local/bin/bash

function test_run
{
  echo "In test_run ....."
}

MODULE_NAME="test"
FUNCTION_NAME="run"

${MODULE_NAME}_${FUNCTION_NAME}

Wow... This works even without eval! Thanks a lot!
