Cons: No interactive editing (view-only).
2.5 xxd – Pre-Installed CLI Hex Tool for Quick Tasks#
Overview: xxd is a minimal CLI tool pre-installed on almost all Linux distros (part of the Vim ecosystem). It’s not a full interactive editor, but it’s essential for converting between binary and hexadecimal formats.
Key Features:
- Convert binary files to hex dumps and vice versa.
- Generate C header files from binary data.
- Support for custom output formats.
- No installation required (pre-loaded).
Basic Usage:
- Create a hex dump:
xxd <filename> > dump.hex - Reverse a hex dump back to binary:
xxd -r dump.hex > restored-file.bin - Generate a C header:
xxd -i <filename> > header.h
Pros: Pre-installed, lightweight, versatile conversion tool.
Cons: No interactive editing (requires editing the dump file manually).
2.6 ImHex – Advanced Hex Editor for Reverse Engineers#
Overview: ImHex is a free, open-source hex editor designed for reverse engineers, programmers, and anyone who values their eyesight during late-night sessions. Written in C++ with Dear ImGui, it's one of the most feature-rich hex editors available on Linux, with over 54k GitHub stars and active development (latest release: v1.38.1, December 2025).
