RAX2(1) 						    BSD General Commands Manual 						   RAX2(1)

NAME

     rax2 -- radare base converter

SYNOPSIS

     rax2 [-ebsSvxkh] [[value] ...]

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

     -e 	 Swap endian.

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

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

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

     -v 	 Show program version

     -x 	 Convert a string into a hash

     -k 	 Keep de same base as the input data

     -h 	 Show usage help message

USAGE

     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 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 ana-
     lyzing programs.
