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.
