free advanced command line hexadecimal editor

 The project aims to create a complete, portable, multi-architecture,
 unix-like toolchain for reverse engineering.
 .
 It is composed by an hexadecimal editor (radare) with a wrapped
 IO layer supporting multiple backends for local/remote files,
 debugger (osx,bsd,linux,w32), stream analyzer, assembler/disassembler
 (rasm) for x86,arm,ppc,m68k,java,msil,sparc code analysis modules and
 scripting facilities. A bindiffer named radiff, base converter (rax),
 shellcode development helper (rasc), a binary information extracter
 supporting (pe, mach0, elf, class, ...) named rabin, and a block-based
 hash utility called rahash.
 .
 This package contains the non gtk version of radare. You won't be able
 to use the ag command for drawing graphs and gradare is missing.
