About:
Tweak is a command-line hex editor that utilizes the ncurses library to provide a full-screen, terminal-based interface for binary file manipulation. It allows users to edit files in either hexadecimal or ASCII representation, with changes synchronized between the two views. The tool is designed for low-level data editing, offering a straightforward and efficient workflow for system administrators and developers.

Key Features:

Full-screen ncurses interface for terminal use
Synchronized hexadecimal and ASCII editing views
Direct raw disk and device file editing capabilities
Simple, keyboard-driven navigation

Use Cases:

Modifying binary configuration files without a GUI
Inspecting and patching compiled executables or libraries
Directly editing raw disk partitions or device files

Alternatives:

hexedit – A similar ncurses-based hex editor with a comparable feature set.
xxd – A command-line tool that can create a hex dump and also revert, but is not an interactive editor.
Bless – A feature-rich graphical hex editor for the GNOME desktop environment.
