The hexer utility is a multi-buffer editor for binary files for Unix-like systems that displays its buffer(s) as a hex dump. The user interface is kept similar to vi/ex.
It can’t (and shouldn’t) be used for editing block devices, because it tries to load the whole file into a buffer.
All POSIX-compatible environments should be supported.
hexer is free and open source software.
Key Features
- Multi buffers.
- Multi level undo
- Command line editing with completion,
- Binary regular expressions.
- The user interface is kept similar to vi, so if you know how to use vi, you’ll get started easily.
