RAX2(1) BSD General Commands Manual RAX2(1)NAMErax2 — radare base converter
SYNOPSISrax2 [-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 analyz‐
ing programs.
