Search files and source code quickly with regular expressions.

Is ripgrep the right tool?

Best for: Searching file contents with regular expressions across a project. It recurses by default and skips .gitignore'd, hidden and binary files, so results stay focused on source. Official source ↗
Look elsewhere when: You need a portable, POSIX-standard tool that is already on every machine. ripgrep's own README recommends grep for that job. Official source ↗

Compared with related CLIs

ast-grep
Choose ast-grep to match code by syntax (abstract syntax tree nodes) instead of text, for example to find or rewrite a call pattern. Official source ↗
fd
Choose fd to find files and directories by name. It matches file names, not file contents. Official source ↗

For your agent

Find relevant code and return line matches or JSON events to an agent.

Structured output: The --json flag emits a stream of JSON messages for search results. Official source ↗
Unattended use: A pattern and explicit path can be supplied as command arguments, without an interactive search interface. Official source ↗
Authentication: This local-file example needs filesystem read access; it does not use a service login. Official source ↗
Platforms: Windows, macOS and Linux. Official source ↗
Limitations: Search skips ignored, hidden and binary files by default. Official source ↗

Try a useful task

Find TODO markers in a project as JSON

Before you start: Install ripgrep using the official instructions and confirm rg is available in your shell. Setup instructions ↗

Run from the project directory you intend to inspect. The dot means that directory; default ignore rules still apply.

rg --json --fixed-strings TODO .

Expected result: JSON messages describe matching lines. Exit status 0 means a match, 1 means no match, and 2 indicates an error. Command reference ↗
