Suppose I want to insert some set of characters as a prefix (or suffix) to all occurrences of a certain substring.

For example, if I have xxx12xxxx345xxxxx6789xxxx

(where x is some non-digit character), and I want to insert the word 'found' before each string of digits to give

xxxfound12xxxxfound345xxxxfound6789xxxx

Using

s/[0-9]*/found/g

will (obviously) just insert found to replace all of the digits. How do I modify the regular expression to keep the digit substring and insert the found, along the lines of

s/[0-9'*/found[something]/g

Thank you, Max
