## What it does

fedit runs targeted file operations from the command line. It can display and search lines, insert text around a match, replace a range, delete content, or move and copy blocks. Locations may be selected with line numbers or text anchors, while `-v` checks each mutation.

The tool is shipped as a dependency-free Go binary and includes structure mapping for multiple languages. It can extract columns from CSV or TSV files and process large logs with `-stream`, reading them line by line and writing through a temporary file. The Go install route requires Go itself, so `go install` will fail until Go is available.

## Install

### Claude Code (native platform)

**Install**
- The MCP registry has no launch command for it: see the repository README

## When to use it
- replace a line range in a configuration file
- insert a block after a matching anchor
- move one function before another block
- extract a column from CSV or TSV data
- rewrite a large log without loading it all

## Example prompts
- Ask the agent to replace lines 30–35 in `server.conf` with `patched-block.txt`, then verify the edit.
- Use fedit to add a rule after `# Custom rules` in `iptables.rules` and run the operation with `-v`.
- Find every `ERROR` line in `huge.log` and change it to `WARN` with `replaceall` and `-stream`.
