Answer 1

You can use move multiple files. I am a maintainer of this project. The syntax is simple.

mmf files*

It will open your $EDITOR with all files names, or vim by default and you can simply highlight the end of all file names using Ctrl+v+G in vim , save the file,quit and that it , all your files are renamed
