#   example: If the original file is "pre-commit", this will run "pre-commit.01", "pre-commit.51", "pre-commit.02.py" but not "pre-commit.tmpl" or "pre-commit01"
# Warning, the regular expression is not like the one we commonly use:
#   -> the dot (.) is not a special character, it really matches a dot
#   -> the star (*) is the wildcard, and does not mean "any number of matches"
#   -> the plus (+) means "at least one match" and must be placed BEFORE the expression
