NAME

4     rax2 — radare base converter
5

SYNOPSIS

7     rax2 [-ebBsSvxkKh] [[expr] ...]
8

DESCRIPTION

10     This command is part of the radare project.
11
12     This command allows you to convert values between positive and negative
13     integer, float, octal, binary and hexadecimal values.
14

OPTIONS

16     -b          Convert from binary string to character (rax2 -b 01000101)
17
18     -k          Keep the same base as the input data
19
20     -e          Swap endian.
21
22     -F          Read C strings from stdin and output in hexpairs. Useful to
23                 load shellcodes
24
25     -i          Dump stdin to C array in stdout (xxd replacement)
26
27     -I          Convert LONG to/from IP ADDRESS
28
29     -l          Append newline to the decoded output for human friendly-ness
30
31     -K          Show randomart key asciiart for values or hexpairs
32
33     -r          Show the same output as the r2's `? 0x804` command.  When
34                 combined with -S (-rS) it will print r2 commands to write the
35                 actual binary into radare2
36
37     -s          Convert from hex string to character (rax2 -s 43 4a 50)
38
39     -S          Convert from character to hex string (rax2 -S C J P)
40
41     -n          Show hexpairs from integer value
42
43     -N          Show hexadecimal C string from integer value
44
45     -u          Convert given value to human readable units format
46
47     -v          Show program version
48
49     -x          Convert a string into a hash
50
51     -h          Show usage help message
52
53     -o          Convert from octal string to char (rax2 -o 162 62)
54

USAGE

56     Force output mode (numeric base)
57
58       =f    floating point
59       =2    binary
60       =3    ternary
61       =8    octal
62       =10   decimal
63       =16   hexadecimal
64
65     Available variable types are:
66
67       int   ->  hex    rax2 10
68       hex   ->  int    rax2 0xa
69       -int  ->  hex    rax2 -77
70       -hex  ->  int    rax2 0xffffffb3
71       int   ->  bin    rax2 b30
72       bin   ->  int    rax2 1010d
73       float ->  hex    rax2 3.33f
74       hex   ->  float  rax2 Fx40551ed8
75       oct   ->  hex    rax2 35o
76       hex   ->  oct    rax2 Ox12 (O is a letter)
77       bin   ->  hex    rax2 1100011b
78       hex   ->  bin    rax2 Bx63
79
80     With no arguments, rax2 reads values from stdin. You can pass one or more
81     values as arguments.
82
83       $ rax2 33 0x41 0101b
84       0x21
85       65
86       0x5
87
88     You can do 'unpack' hexpair encoded strings easily.
89
90       $ rax2 -s 41 42 43
91       ABC
92
93     And it supports some math operations.
94
95       $ rax2
96       0x5*101b+5
97       30
98
99     It is a very useful tool for scripting, so you can read floating point
100     values, or get the integer offset of a jump or a stack delta when analyz‐
101     ing programs.
