Usage

All r2 tools and commands support printing the output in different formats by appending a character at the end or using the -r (*r2) and -j (json) flags.

radare2

r2 -       # same as r2 malloc://4096; "the playground"
r2 /bin/ls # standard way to run r2
r2 -w ls   # open in read-write
r2 -d ls   # start debugging the ls in PATH

rasm2

rasm2 -L                 # list all supported assembler/disassembler/emulator plugins
rasm2 -a arm -b 64 'nop' # assemble a nop in 64-bit ARM
rasm2 -d 90              # disassemble 0x90; nop, if you're using x86

rabin2

rabin2 -s /bin/ls # list symbols in a binary
rabin2 -z /bin/ls # find strings

rax2

rax2 '10+0x20' # compute the result
rax2 -k 10+32  # keep the same base as input (10)
rax2 -h        # convert between (hex, octal, decimal.. bases)

Scripting

There are native API bindings available for many programming languages, but it is recommended to use r2pipe which is a simple interface to execute r2 commands and get the output in result. Appending a j in the commands the output will be in JSON, so it can be parsed with .cmdj()

Some of the languages supported by r2 are: Python, Ruby, JavaScript, Lua, Perl, PHP, V, Go, Rust, Swift, C#, Java, Shell, OCaml, Haskell, Scheme (Guile), Common Lisp, Clojure, Erlang, D, Vala/Genie, Prolog, Nim, Newlisp...

import r2pipe
r2 = r2pipe.open("/bin/ls")
print(r2.cmd("pd 10"))
r2.quit()
