Regex Editor & Tester

This regular expression matches absolute Unix-style file paths by ensuring the string starts with a forward slash followed by one or more alphanumeric characters, underscores, hyphens, or dots. It enforces strict directory or file name formatting by repeating this pattern for the entire length of the string until the end. It is commonly used for validating path inputs in Node.js environments or web applications where relative paths, spaces, or special characters are not permitted.
