NAME

       udcli  -  A  CLI  tool  for  quick  disassembly  of  x86  and x86-64 class instruction set
       architectures.

SYNOPSIS

       udcli [-option(s)] file

DESCRIPTION

       udcli is a CLI front-end to the Udis86 Disassembler library.

OPTIONS

       -16    Set the disassembly mode to 16 bits.

       -32    Set the disassembly mode to 32 bits.  (default)

       -64    Set the disassembly mode to 64 bits.

       -intel Set the output to INTEL (NASM like) syntax.  (default)

       -att   Set the output to AT&T (GAS like) syntax.

       -v <v> Set vendor.  <v> = {intel, amd}.

       -o <pc>
              Set the value of the program counter to <pc>.  (default = 0)

       -s <n> Set the number of bytes to skip before disassembly to <n>.

       -c <n> Set the number of bytes to disassemble to <n>.

       -x     Set  the  input  mode  to  whitespace  separated  8-bit  numbers   in   hexadecimal
              representation.  Example: 0f 01 ae 00

       -noff  Do not display the offset of instructions.

       -nohex Do not display the hexadecimal code of instructions.

       -eflags
              Display information on EFLAGS register.

       -access
              Display access information on operand.

       -implicit
              Display implicit registers used or modified by the instruction.

       -h     Display this help message.

       --version
              Show version

Example

       Usage example:

              echo "65 67 89 87 76 65 54 56 78 89 09 00 90" | udcli -32 -x

       will result in output such as this:

              0000000080000800 656789877665     mov [gs:bx+0x6576], eax
              0000000080000806 54               push esp
              0000000080000807 56               push esi
              0000000080000808 7889             js 0x80000793
              000000008000080a 0900             or [eax], eax
              000000008000080c 90               nop
