There are many ways to bulk rename files in Linux. Some with command line magic, some via a graphical user interface. A useful utility that I have found is something kind of in between both methods.
First, you must install
renameutils and use
qmv with your favorite text editor. In Ubuntu this can be done with
sudo apt install renameutils but depending on your distribution you may need to install via different command lines.
qmv loads all names in your editor and when you save and close it applies your changes to the actual files. If the changes are inconsistent (e.g. two files get the same name) it will abort without touching anything. It also handles circular renames correctly. I usually do:
$ qmv -f do
So that it shows just one column of names (do: destination-only). Here’s how it looks:
If you combine it with the multiple cursors of SublimeText, Atom or Visual Studio Code, it makes a very nice and powerful tool for bulk renaming. For instance, for Atom, you would do
EDITOR="atom -w" qmv -f do.
