|
|
.Sh OPTIONS
|
|
.Bl -tag -width Fl
|
|
.It Fl b
|
|
Convert from binary string to character (rax2 \-b 01000101)
|
|
.It Fl k
|
|
Keep the same base as the input data
|
|
.It Fl e
|
|
Swap endian.
|
|
.It Fl F
|
|
Read C strings from stdin and output in hexpairs. Useful to load shellcodes
|
|
.It Fl i
|
|
Dump stdin to C array in stdout (xxd replacement)
|
|
.It Fl I
|
|
Convert LONG to/from IP ADDRESS
|
|
.It Fl l
|
|
Append newline to the decoded output for human friendly-ness
|
|
.It Fl K
|
|
Show randomart key asciiart for values or hexpairs
|
|
.It Fl r
|
|
Show the same output as the r2's `? 0x804` command.
|
|
When combined with -S (-rS) it will print r2 commands to write the actual binary into radare2
|
|
.It Fl s
|
|
Convert from hex string to character (rax2 \-s 43 4a 50)
|
|
.It Fl S
|
|
Convert from character to hex string (rax2 \-S C J P)
|
|
.It Fl n
|
|
Show hexpairs from integer value
|
|
.It Fl N
|
|
Show hexadecimal C string from integer value
|
|
.It Fl u
|
|
Convert given value to human readable units format
|
|
.It Fl v
|
|
Show program version
|
|
.It Fl x
|
|
Convert a string into a hash
|
|
.It Fl h
|
|
Show usage help message
|
|

.Pp
|
|
Available variable types are:
|
|
.Pp
|
|
int \-> hex rax2 10
|
|
hex \-> int rax2 0xa
|
|
\-int \-> hex rax2 \-77
|
|
\-hex \-> int rax2 0xffffffb3

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
|
|
.Pp
|
|
With no arguments, rax2 reads values from stdin. You can pass one or more values
|
|
as arguments.
|
|
.Pp
|

|
|
0x21
|
|
65
|
|
0x5
|
|
.Pp
|
|
You can do 'unpack' hexpair encoded strings easily.
|
|
.Pp
|
|
$ rax2 \-s 41 42 43
|
|
ABC
|
|
.Pp
|
|
And it supports some math operations.
|
|
.Pp
|
|
$ rax2
|
|
0x5*101b+5
|
|
30
|
|
.Pp
