NAME
       x86dis - disassemble a bytestream of Intel x86 instructions

SYNTAX
       x86dis [-a offset|--addr=offset]
	      [-r offset len|--range=offset len]
	      [-e offset|--entry=offset]
	      [-s name|--syntax=name]
	      [-d name|--desc=name]
	      [-f file|--file=file]
	      [-o file|--out=file]
	      [-l file|--log=file]
	      [-p num|--pagesize=num]
	      [-h|-?|--help]
	      [-v|--version]

DESCRIPTION
       A command-line interface to the libdisasm disassembler library.

OPTIONS
       At least one option from the list -a, -e, -r must be given.

       -f, --file=file
	      Read input bytes from file instead of stdin

       -o, --out=file
	      Write output to file instead of stdout

       -l, --log=file
	      Log errors to file instead of stderr

       -p, --pagesize=num
	      Set page size for buffering STDIN to num (default 512K)

       -s, --syntax=name
	      Set output syntax to name, where name is one of intel
	      (Intel syntax), att (AT&T syntax), raw (libdisasm syntax)

       -d, --desc=name
	      Print a description of syntax name

       -a, --addr=offset
	      Disassemble single instruction at offset

       -e, --entry=offset
	      Disassemble forward from offset

       -r, --range=offset len
	      Disassemble len bytes starting at offset

       All  offset  and  len  parameters  are expected to follow the conventions used in strtoul(3), where hexadecimal numbers have the prefix 0x,
       octal numbers have the prefix 0, and decimal numbers have no prefix. A value of 0 for len indicates that that range extends to the  end	of
       the file.

EXAMPLES
       cat `which ls` | x86dis -s intel -e 0x00 -r 0x00 -1 -a 0xEEEE
       x86dis -e 0 -s intel < bootsect.img
       x86dis -d -s raw -f a.out -e `readelf -h a.out |
	     grep  Entry  |   awk  '{ printf( "0x%%x",	     strtonum($4) - 0x8048000 ) }` echo '55 89 e5 83 EC 08' | perl -ane 'foreach(@F){print
       pack("C",hex);}'| x86dis -e 0 -s att

NOTES
       x86dis performs no file format parsing, nor any verification that its input is in fact executable binary code. All offsets are  assumed	to
       be  from  the  start  of the file, with no load addresses applied. The intent is to provide a bytestream disassembler rather than an object
       file disassembler.

       Descriptions of the various output formats can be obtained using the -d option.
