RASM2(1) BSD General Commands Manual RASM2(1)NAMErasm2 — radare2 assembler and disassembler tool
SYNOPSISrasm2 [-ABdDeEfCLvwrq] [-a arch] [-b bits] [-c cpu] [-F in:out]
[-o offset] [-O ofile] [-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
-A Show analysis information of given hexpair string
-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)
-E Output disassembled instructions in ESIL format.
-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.
-hh Show long help message including supported assembler direc‐
tives
-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)
-O ofile output to file, for example 'rasm2 -BF a a.asm'
-r Show output in r2 script
-s syntax Select syntax output (intel, att)
-w Describe opcode (whats op)
-q Quiet output (handy for -L, -v, ...)
different than filename-.intel_syntax
Use intel syntax rather than att:w
-.att_syntax
Use ATT syntax rather than flu :w dentify the region fof
aslerrger
-string dentify the region fof aslerrger
-.ascii
-.align
-.arm
-.thumb
-.arch
-.bits
-.fill
-.kernel
-.os
-.hex
-.int16
-.short
-.int32
-.int64
-.glob
-.equ
-.org
-.text
-.data
EXAMPLES
Assemble opcode:
$ rasm2-a x86 -b 32 'mov eax, 33'
Disassemble opcode:
$ rasm2-d 90
