RAX2(1)

NAME
rax2 - radare base converter

SYNOPSIS
rax2 [-ebBsSvxkKh] [[expr] ...]

DESCRIPTION
This command is part of the radare project.

This command allows you to convert values between positive and negative integer, float, octal, binary and hexadecimal values.

OPTIONS

-b  Convert from binary string to character (rax2 -b 01000101)

-k  Keep the same base as the input data

-e  Swap endian.

-F  Read C strings from stdin and output in hexpairs. Useful to load shellcodes

-l  Append newline to the decoded output for human friendly-ness

-K  Show randomart key asciiart for values or hexpairs

-s  Convert from hex string to character (rax2 -s 43 4a 50)

-S  Convert from character to hex string (rax2 -S C J P)

-n  Show hexpairs from integer value

-N  Show hexadecimal C string from integer value

-u  Convert given value to human readable units format

-v  Show program version

-x  Convert a string into a hash

-h  Show usage help message

USAGE

Force output mode (numeric base)

=f floating point =2 binary =3 ternary =8 octal =10 decimal =16 hexadecimal

Available variable types are:

int -> hex rax2 10 hex -> int rax2 0xa -int -> hex rax2 -77 -hex -> int rax2 0xffffffb3 int -> bin rax2 b30 bin -> int rax2 1010d float -> hex rax2 3.33f hex -> float rax2 Fx40551ed8 oct -> hex rax2 35o hex -> oct rax2 Ox12 (O is a letter) bin -> hex rax2 1100011b hex -> bin rax2 Bx63

With no arguments, rax2 reads values from stdin. You can pass one or more values as arguments.

$ rax2 33 0x41 0101b 0x21 65 0x5

You can do 'unpack' hexpair encoded strings easily.

$ rax2 -s 41 42 43 ABC

And it supports some math operations.

$ rax2 0x5*101b+5 30

It is a very useful tool for scripting, so you can read floating point values, or get the integer offset of a jump or a stack delta when analyzing programs.
