ddhx is a keyboard-driven modal terminal hex editor designed to handle both ordinary binary files and very large data sets. Its interface combines direct byte editing with selection and range-oriented commands.
The editor supports several character representations alongside hexadecimal data, making it useful for binaries containing text encoded for older or specialised systems. Search functionality uses a pattern syntax rather than being limited to simple byte strings.
ddhx also distinguishes between different types of input media so operations that would not make sense for a disk, device or stream can be restricted appropriately.
This is free and open source software.
