Very interesting, I’ll definitely give it a try!

Another approach I recently discovered is an old but beautiful Unix-style tool for renaming files: vidir - edit a directory in your text editor. It’s part of the moreutils suite [1].

You get the list of filenames in your editor – edit them as you like, save, exit, and it renames the files. It uses whatever editor is set in your $EDITOR env var, so it doesn’t have to be vi/vim.

You can also pipe in a list of files, e.g. `find . -type f | vidir -`, to edit just the files you want - and you can even change paths (add, rename, remove directories) in the editor to move files around easily.

To try it quickly on macOS: `brew install moreutils`

I'm not sure how "powerful" vidir is, but I recently found this functionality in yazi [1] and it became one of those "you think you don't need it until you try it" features

This is also integrated into Emacs with dired, and it’s pretty neat [0].

oh wow, this feels like https://github.com/stevearc/oil.nvim

if you can forgive a shameless plug, I wrote https://github.com/ddlsmurf/fled some time ago and it serves me very well to this day. (It's not half as advanced as OP's tool but still useful)

Incredible name choice here - it's very rare that I get this feeling associating a new project with its name. I'm filled with feelings that touch on nostalgia, utility, UX design history and computing heritage when I hear the name F2 associated with a batch renaming tool. Great job!

Thank you! I knew I had a winner the moment it popped into my head :)

It's indeed a name that immediately rings the right bell, without being an ungoogleable common noun or verb. Kudos.

(Though for those of us who cut their teeth on tools like Norton Commander on the original IBM PC, the association would be with F6.)

Oh! Then maybe that’s why IntelliJ likes Shift+F6 for renaming by default?

Awesome tool, thanks for sharing. One feature I would love to see on renaming tools is the following:

  -A - Sample of the of the ACTUAL file name
  -B - Sample of the desired filename

e.g.

  f2 -A 001.pdf -B 001_renamed.pdf

and this would automatically determine that every file with this "pattern" (001) should get the renamed prefix, so:

  001.pdf => 001_renamed.pdf
  002.pdf => 002_renamed.pdf
  ...

Sounds weird, but there once was a tool written in dotnet that used machine learning techniques to achieve exactly this and it worked like a charm. Unfortunately I lost the reference and never found it again.

Most important: Worked locally and did not send the filenames to chatGPT ;)

You can already do this with F2 by using capture variables:

  f2 -f '(\d+).pdf' -r '{$1}_renamed.pdf'

Does that align with what you're looking for?

Thank you, unfortunately, that's not the point :-) I knew I could do this with a regex.

The advantage of using a sample instead of a regex is, that you don't need to think about it. I have "this.pdf" and I want "that.pdf" is way easier than developing a regex that matches the parts I need replacing it with what I want.

The tool I mentioned afaik used machine learning to determine a valid regex from a given sample automagically somehow (see [1]), which was then applied to the files it found, followed by a preview and a choice to either perform or abort. You could also provide more examples, if it did not succeed determining the regex in the first place to be more specific:

   f2 -A 001.pdf -B 001_renamed.pdf -A 002.pdf -B 002_renamed.pdf

It was awesome, unfortunately otherwise not suitable for my needs (windows only or something)

I should have saved it somewhere to re-implement it myself. The only things I remember are, that it was dotnet based, using the dotnet machine learning libs and it was a command line tool. Maybe it was called `ab` because you could provide the parameter -A sample -B destination, but I did not find anything on github.

If I ever find it again, I'll let you know in a github issue.

Dry-run by default! Use of metadata like EXIF! Undo!

Here's some great product and UX chops, not just coding chops.

I really like your CLI design here, clearly extremely well thought out, lots of great taste on display here: https://f2.freshman.tech/guide/tutorial

The EXIF stuff to create folders based on the date photos were taken is fantastic! https://f2.freshman.tech/guide/organizing-image-library

This tool solves a problem that I face all the time, I am definitely going to be using this often.

Thanks a lot Simon! I'm really thrilled to hear it's hitting the mark for you :)

For photos, I'm guessing you can use Exiftool's built in geolocation feature to add the city and country first.

Small typo: the example given for "--replace-limit -1" reads:

    abc_abc.txt | 123_abc.txt

but it should probably say:

    abc_abc.txt | abc_123.txt

Funnily enough, the triplet example given in the tutorial for "--replace-limit" [1] (replacing either the first or the last of "abc_abc_abc") is written so that it has the effect of driving the reader to wonder "Ok but, what about the middle one????" :)

A small idea for an alternative, more flexible option: "--replace-range", where you could use a well established syntax to represent ranges such as the one from Python and Go slices, so it's not only possible to replace from the leftmost or rightmost but also in-between.

FYI, Double Commander (x-platform, foss) has Multi Rename Tool which is clone of Total Commanders feature. It supports AFAICS all the feature of F2 + plugins that can get arbitrary info about files.

Wow, this goes instantly to my toolbox. Thanks for writing this and sharing it!

It only happens a few times a year that I need to batch rename. Buy when I do my adrenaline levels go up by about two espressos.

Wow, it can integrate with exiftool. I use exiftool to rename photo files, but I think f2 offers more flexible renaming features.

Thanks for making f2, I've been using it for a while and it's saved me so much time!

In windows I use PowerToys - power rename to rename files. But I'm not a power user I rarely need renaming something.

The undo functionality is a nice touch. I know cuz I write scripts to rename files and made mistakes before.

Really nice, wow.

Honestly I don't see myself remembering and using the variables features(which gives the exiftool feature others here are raving about) but it's already insanely good without that. Love the ability to refine your selection with further -f flags. Also the ability to rename while create nested paths is so good.

Suggestion, having an "up"[1] mode where you can see the dry run output in a live updating thing when you are adding further -fs and -rs.
