NAME¶
rax2
—
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
-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.
