F2
F2 batch-renames files and directories through a cross-platform command-line tool written in Go.
About F2
F2 is a free, open source command-line tool for renaming many files and directories at once. It is written in Go and is described by its project as cross-platform. Renaming runs as a dry run by default, so the proposed changes can be reviewed before they are applied.
F2 supports simple string replacements and regular expressions. It can use file attributes, such as EXIF data for images and ID3 tags for audio files, in the new names. Each rename is checked for conflicts before it runs, and detected conflicts can be resolved automatically. Any rename operation can be undone. Go developers can install it with go install, which requires Go 1.23 or later. Pre-compiled binaries for several operating systems are available from the project's releases page.
