To help you with your question, you'll need to give us a bit more detail:

• Where are you searching for this pattern? In a file? In a string stored in a variable?
• When you find this pattern what information do you need to keep about it? Its position in a string/file? The number after "test"?

In the meantime, you may find perlretut helpful. It explains how to use regular expressions to search for patterns in strings.

Best, beth
