I really like the approach of pipe-rename ( https://github.com/marcusbuffett/pipe-rename ) for renaming many files. It's especially convenient for people who can efficiently edit many lines in their favorite text editor (so everybody here, I guess). Main problem: you maybe don't do this kind of operation frequently enough to remember how it's called or how you aliased it.

  $ ls / find # tweak until I have a list of things to rename
  $ for file in $(ls / find...); do echo "mv $file $(echo $file | sed ... )"; done # this prints mv commands for renaming, I can inspect them as needed
  $ for file in $(); do...; done | sh # execute the renaming

The demo requires a sufficiently smart editor. But with a sufficiently smart editor you can prepare a script and pipe it into an interpreter.

I like that idea of converting metadata to text, so you can do text operations on it that you are already familiar with, and then apply the changes back. If your problem can be solved by just regexps, there's a "rename" tool installed by Perl I've used for decades. E.g. rename -n 's/JPEG$/jpg/' *JPEG Will apply the substitution for JPEG at end of the filename to just jpg. The -n will run without renaming so you can s…

It is a good approach. Emacs has dired and other modes for doing this.

To expand on this: if you look at a dir in Emacs then change the buffer to be writable, you can change file names and saving the buffer renames files. You can also edit the permissions columns in a similar way. And there is vc integration so eg eMacs will hg mv files in a mercurial repo.
