In Intuitive find and replace CLI (sed alternative)Show HN: F2 – Cross-Platform CLI Batch Renaming Tool
Hey HN!
I'm excited to share f2, a command-line tool I built for fast and flexible bulk renaming of files. It's cross-platform (Linux, macOS, Windows), executes a dry-run by default, supports undo, and provides great flexibility in file renaming with several built-in variables and Exiftool integration.
I hope you find it useful!

Hey HN!
I'm excited to share f2, a command-line tool I built for fast and flexible bulk renaming of files.

If you've ever struggled with renaming large batches of files or wished for more control and speed when managing file names, this might be just what you need. I hope you find it useful!

In New(ish) command line toolsF2: Command-line batch renaming tool
1 points · Open discussionThis resonates with me. I recently published a cross-platform tool [1] for bulk renaming files with dry run as the default. In this mode, it shows the changes about to be made and any possible problems that may occur (such as overwriting existing files). To actually carry out the changes a flag must be used.
I felt it was a good design decision since the effects of bulk renaming can be substantial. Most other similar tools have it backwards with their dry-run mode relegated to a secondary action.
