Regex Editor & Tester

This regex matches the lowercase letter 's' immediately followed by a single digit, capturing the digit in a group. It is commonly used for pattern matching in text processing, such as finding version numbers, identifiers, or codes like 's1', 's2', etc. With the 'g' and 'm' flags, it finds all matches across multiple lines, useful for search-and-replace operations or extracting data from logs and configuration files.
