grep
Search file contents using regex patterns. Detects encoding, recurses directories, and can show context lines.
Instructions
Searches file contents for a regex pattern. Encoding-aware: auto-detects file encoding. Can search a single file or recursively search a directory. Output modes: content (default, matching lines), files_with_matches (paths only), count (match counts). Context: use before/after/context to include surrounding lines (like grep -B/-A/-C).
