But the emacs way is better: open the directory in dired, press c-c c-c, you're now in edit mode, that is, the buffer with the directory listing is now fully editable, apply any modifications, press c-c c-c again to save the buffer, thus renaming the files.
Is there a tool for the #Linux command line that helps me mass rename files *semi-manually*? I'm imagining something that lists the file names in my $EDITOR of choice, letting me edit them, and upon saving and exiting, applies the renames.
For example: I have a sequence of files with 0-based indices, and I want to change it to 1-based indices. There aren't many files, so it's quicker to do this in vim than it is to write a script. But typing 20 "mv" commands, even with tab completion, is slow.
