fileobj is an ncurses-based hex editor with a vi-style interface. It is designed for keyboard-driven binary editing and supports regular files as well as block devices.
The program can work with only part of a file by specifying an offset and length, which is useful when examining large files or disk images. It also supports several buffers and windows, allowing different parts of binary data to be inspected during the same session.
Its command set covers both basic byte manipulation and more specialised binary-analysis tasks while retaining familiar vi-inspired navigation.
This is free and open source software.
