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     -l          Append newline to the decoded output for human friendly-ness
26
27     -K          Show randomart key asciiart for values or hexpairs
28
29     -s          Convert from hex string to character (rax2 -s 43 4a 50)
30
31     -S          Convert from character to hex string (rax2 -S C J P)
32
33     -n          Show hexpairs from integer value
34
35     -N          Show hexadecimal C string from integer value
36
37     -u          Convert given value to human readable units format
38
39     -v          Show program version
40
41     -x          Convert a string into a hash
42
43     -h          Show usage help message
44
45     -o          Convert from octal string to char (rax2 -o 162 62)
46

USAGE

48     Force output mode (numeric base)
49
50       =f    floating point
51       =2    binary
52       =3    ternary
53       =8    octal
54       =10   decimal
55       =16   hexadecimal
56
57     Available variable types are:
58
59       int   ->  hex    rax2 10
60       hex   ->  int    rax2 0xa
61       -int  ->  hex    rax2 -77
62       -hex  ->  int    rax2 0xffffffb3
63       int   ->  bin    rax2 b30
64       bin   ->  int    rax2 1010d
65       float ->  hex    rax2 3.33f
66       hex   ->  float  rax2 Fx40551ed8
67       oct   ->  hex    rax2 35o
68       hex   ->  oct    rax2 Ox12 (O is a letter)
69       bin   ->  hex    rax2 1100011b
70       hex   ->  bin    rax2 Bx63
71
72     With no arguments, rax2 reads values from stdin. You can pass one or more
73     values as arguments.
74
75       $ rax2 33 0x41 0101b
76       0x21
77       65
78       0x5
79
80     You can do 'unpack' hexpair encoded strings easily.
81
82       $ rax2 -s 41 42 43
83       ABC
84
85     And it supports some math operations.
86
87       $ rax2
88       0x5*101b+5
89       30
90
91     It is a very useful tool for scripting, so you can read floating point
92     values, or get the integer offset of a jump or a stack delta when analyz‐
93     ing programs.
