Regex vs. Wildcards: Which one do you need?

Both are used for pattern matching, but they differ significantly in power, complexity, and common use cases.

1. Wildcards (Globbing)

Wildcards are the "simple" version of pattern matching. You mostly use them in file systems or command lines. They use special characters like * and ?.

• * matches any number of characters.
• ? matches exactly one character.

Example: Searching for *.jpg finds all JPEG files. It's fast and easy to remember.

2. Regular Expressions (Regex)

Regex is a sophisticated language for matching patterns within strings. It's used by developers for validation, scraping, and complex text manipulation.

• ^ and $ for start/end of line.
• \d+ for matching one or more digits.
• [a-z]{3,5} for matching 3 to 5 lowercase letters.

Example: ^[a-zA-Z0-9+_.-]+@[a-zA-Z0-9.-]+$ is a basic pattern for an email address. Wildcards can't do this easily.
