About:
Massren is a command-line utility that allows users to rename multiple files simultaneously by opening them in their default text editor. It automatically detects changes made to filenames within the editor and executes the rename operations upon saving and closing the file. This workflow streamlines complex batch renaming tasks that are difficult to express with standard shell commands.
Key Features:
  • Uses your favorite text editor for renaming
  • Handles complex rename patterns easily
  • Automatic detection of rename operations
  • Command-line interface for scripting
Use Cases:
  • Batch renaming files with complex naming patterns
  • Organizing large directories of photos or documents
  • Refactoring project file structures
Alternatives:
  • rename – Uses Perl regex syntax, requires learning specific flags
  • qmv – Part of renameutils, opens file list in editor but with different workflow
