RAGG2(1)

NAME
ragg2 - radare2 utility to run programs in exotic environments

  SYNOPSIS

  DESCRIPTION
ragg2 is a frontend for r_egg, compile programs into tiny binaries for x86-32/64 and arm. This tool is experimental and it is a rewrite of the old rarc2 and rarc2-tool programs as a library and integrated with r_asm and r_bin. Programs generated by r_egg are relocatable and can be injected in a running process or on-disk binary file. ragg2-cc is another tool that comes with r2 and it is used to generate shellcodes from C code. The final code can be linked with rabin2 and it is relocatable, so it can be used to inject it on any remote process. ragg2-cc is conceptually based on shellforge4, but only linux/osx x86-32/64 platforms are supported.

  DIRECTIVES
The rr2 (ragg2) configuration file accepts the following directives, described as key=value entries and comments defined as lines starting with '#'. set architecture x86, arm 32 or 64 windows, linux or osx select binary format (pe, elf, mach0) output file to write result of compilation specify shellcode name to be used (see -L) specify encoder name to be used (see -L) specify shellcode as hexpairs set configure option for the shellcode encoder. The argument must be key=value. include contents of file Patch final buffer with given dword at specified offset Patch final buffer with given qword at specified offset Patch final buffer with given hexpairs at specified offset Specify generic paddings with a format string. autodetect native file format (osx=mach0, linux=elf, ..) use default output file (filename without extension or a.out) add include path show assembler code execute (just-in-time)

  EXAMPLE
  $ cat hi.r
  /* hello world in r_egg */
  write@syscall(4);
  exit@syscall(1);
  main@global(128) {
    .var0 = "hi!\n";
    write(1,.var0, 4);
    exit(0);
  }
  $ ragg2 -O -F hi.r
  $ ./hi
  hi!
  $ cat hi.c
  main() {
    write(1, "Hello, 6);
    exit(0);
  }
  $ ragg2 hi.c
  $ ./hi.c.bin
  Hello
