## What it is
Massren is a cross-platform command line tool for renaming multiple files by editing a generated filename list in your own text editor. It supports undo, dry-run mode, moving files into subdirectories, and safety checks against accidental renames.

## Use cases
- batch rename files using my text editor instead of regex tools
- rename hundreds of photos at once from the command line
- dry run a bulk file rename before applying it
- undo a multi-file rename operation
- move files into subdirectories while renaming them
- rename files with vim or sublime instead of learning a rename syntax

## When to choose
- you prefer editing filenames in a familiar text editor over learning regex rename syntax
- you need cross-platform bulk renaming on Linux, macOS, or Windows
- you want undo and dry-run safety for mass rename operations

## When to avoid
- you need a GUI rename tool with live preview
- you only need to rename one or two files
- you need prebuilt Windows binaries (discontinued since v1.3)
