TLDR

Open a file in the hex editor

$ hexabyte [path/to/file]

Open a single file in split screen view

$ hexabyte -s [path/to/file]

Open two files side-by-side for diff

$ hexabyte [path/to/file1] [path/to/file2]

Use a custom config file

SYNOPSIS

hexabyte [options] file [file2]

hexabyte is a modern, modular, and robust TUI hex editor designed for modifying file contents at the byte level. It supports viewing and editing in hexadecimal, UTF-8 text, and binary with multiple display modes: single file editing, split view for side-by-side panes on one file, and diff mode when two files are opened together.The editor features a plugin architecture for extensibility and provides standard hex editing operations including inserting, deleting, and replacing bytes, as well as selecting and copy/pasting byte ranges.

PARAMETERS

-s, --split

Display a single file in two split-screen editors.

-c, --config FILE

Use a custom config file (default: `~/.config/hexabyte/config.toml`).

-h, --help

Show help message and exit.

CAVEATS

Requires Python 3.10+. Very large files may impact performance. The diff mode highlights byte-level differences, which may produce noisy output for structurally different files.

HISTORY

hexabyte was created by thetacom and is written in Python. It was designed to provide a modern, extensible alternative to traditional terminal hex editors.
