# 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](https://github.com/radareorg/radare2-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...
|
|
|
|
```python
|
|
import r2pipe
|
|
r2 = r2pipe.open("/bin/ls")
|
|
print(r2.cmd("pd 10"))
|
|
r2.quit()
|
|
```
