bvi

If you're looking for an easy-to-use CLI based editor for binary files, based on the world-renowned vi text editor, then bvi should be your go-to software. With bvi, all you need to do is start the editor and begin to edit. If you're familiar with vi, you'll find the interface extremely easy to use.

The bvi software package also comes with a bmore program, which is an added bonus for those who use CLI extensively. However, if you've never heard of vi before, you might want to consider using a different software package instead. While bvi is undoubtedly an excellent software, it's primarily intended for those who are well-versed in the use of vi.
