Usage: rz-asm [-ACdDehLBvw] [-a arch] [-b bits] [-m plugin] [-o addr] [-s syntax]
[-f file] [-F fil:ter] [-i skip] [-l len] 'code'|hex|-
-a arch Set architecture to assemble/disassemble (see -L)
-A Show Analysis information from given hexpairs
-b bits Set cpu register size (8, 16, 32, 64) (RZ_ASM_BITS)
-B Binary input/output (-l is mandatory for binary input)
-c cpu Select specific CPU (depends on arch)
-C Output in C format
-d, -D Disassemble from hexpair bytes (-D show hexpairs)
-e Use big endian instead of little endian
-I Display lifted RzIL code (same input as in -d, IL is also validated)
-E Display ESIL expression (same input as in -d)
-f file Read data from file
-F in:out Specify input and/or output filters (att2intel, x86.pseudo, ...)
-h, -hh Show this help, -hh for long
-i len Ignore N bytes of the input buffer
-j Output in JSON format
-k kernel Select operating system (linux, windows, darwin, ..)
-l len Input/Output length
-L List Asm plugins: (a=asm, d=disasm, A=analyze, e=ESIL, I=RzIL)
-m plugin List supported CPUs for the chosen plugin
-o, -@ addr Set start address for code (default 0)
-O file Output file name (rz-asm -Bf a.asm -O a)
-p Run SPP over input for assembly
-q Quiet mode
-s syntax Select syntax (intel, att)
-v Show version information
-x Use hex dwords instead of hex pairs when assembling.
-w Describe opcode
If '-l' value is greater than output length, output is padded with nops
If the last argument is '-' reads from stdin
Environment:
RZ_ARCH e asm.arch # architecture to assemble/disassemble (same as rz-asm -a)
RZ_ASM_ARCH # architecture to assemble/disassemble (same as rz-asm -a)
RZ_ASM_BITS # cpu register size (8, 16, 32, 64) (same as rz-asm -b)
RZ_BITS e asm.bits # cpu register size (8, 16, 32, 64) (same as rz-asm -b)
RZ_DEBUG # if defined, show error messages and crash signal
RZ_NOPLUGINS # do not load shared plugins (speedup loading)
