grepatch is a command-line patch tool that processes grep output to apply text replacements to files.

// Replace text using sed
$ git grep -n "old_text" | sed 's/old_text/new_text/g' | grepatch

// Edit matches manually in your preferred editor
$ git grep -n "function_name" | grepatch --edit

grepatch transforms the grep-formatted output (with line numbers) into file modifications. It's perfect for making consistent changes across multiple files in a codebase.

• Process grep output: Works seamlessly with the output format from grep -n, git grep -n and similar tools
• Batch editing: Apply text changes to multiple files in a single operation
• Interactive editing: Use your preferred text editor to manually review and modify changes before applying them
• Minimal dependencies: Simple and focused tool that integrates with standard Unix tools
