NAME rasm2 -- radare2 assembler and disassembler tool SYNOPSIS rasm2 [-ABdDeEfCLvwrNqx] [-a arch] [-b bits] [-c cpu] [-F in:out] [-o offset] [-@ 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 loaded asm plugins -s offset Offset of the opcode to assemble (default is 0) -@ offset Alias for -s -N Dont load any plugin, same as R2_NOPLUGINS=1 or r2 -NN -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, masm, ...) -w Describe opcode (whats op) -x Use hex dwords instead of hexpairs in the assembler output -q Quiet output (handy for -L, -v, ...) DIRECTIVES List the supported assembler and preprocessor directives with: $rasm2 -hh EXAMPLES Assemble opcode: $ rasm2 -a x86 -b 32 'mov eax, 33' Disassemble opcode: $ rasm2 -d 90 SEE ALSO radare2(1) AUTHORS pancake <pancake@nopcode.org> Sep 5, 2024 RASM2(1)
