X86DIS(1)			   libdisasm			     X86DIS(1)

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 dis-
       assembler.

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