NAME

       rasm2 - radare2 assembler and disassembler tool

                                                                                                        RASM2(1)

SYNOPSIS

       rasm2  [-dDfBCLevw]  [-F  in:out]  [-o offset] [-a arch] [-b bits] [-c cpu] [-s syntax] [-i int] [-l int]
             [ARG]

DESCRIPTION

       This tool uses r_asm to assemble and disassemble files or hexpair strings. It supports a  large  list  of
       architectures which can be listed using the -L flag.

       -a arch     Set architecture plugin

       -b bits     Set architecture bits

       -B          Binary input/output (-l is mandatory for binary input)

       -c cpu      Select specific CPU (depends on -a arch)

       -C          Output in C format

       -d          Disassemble hexpair bytes. rasm2 -d 9090

       -D          Disassemble showing hexpair and opcode

       -e          Use big endian (or swap endianness if used more than once)

       -f          Read data from file instead of ARG.

       -F in:out   Specify input and/or output filters (att2intel, x86.pseudo, ...)

       -h          Show usage help message.

       -l int      Input/Output length

       -i int      Ignore/skip N bytes from the beginning of the input buffer

       -L          List supported asm plugins

       -o offset   Offset of the opcode to assemble (default is 0)

       -s syntax   Select syntax output (intel, att)

       -w          Describe opcode (whats op)

EXAMPLES

       Assemble opcode:

         $ rasm2 -a x86 -b 32 'mov eax, 33'

       Disassemble opcode:

         $ rasm2 -d 90
