A wrapper to use objdump for raw i8086 disassembling with intel syntax.

disasm

#! /bin/bash

if [ $# -lt 1 ] || [ $# -gt 3 ]
then
  printf 'usage:\n  %s <file> [offset [limit|(+|-)length]]\n' `basename $0`
  exit 1
fi

IN="$1"
START=0
STOP=`du -b $IN | cut -f1`

if [ $# -gt 1 ]
then
  START=$2
  if [ $# -gt 2 ]
  then
    if [ ${3:0:1} == '+' ]
    then
      STOP=$(($START + ${3:1}))
    elif [ ${3:0:1} == '-' ]
    then
      STOP=$START
      START=$(($STOP - ${3:1}))
    else
      STOP=$3
    fi
    STOPOPT="--stop-address=$STOP"
  fi
  STARTOPT="--start-address=$START"
fi

printf '%s 0x%x:0x%x (%d)\n' $IN $START $STOP $(($STOP - $START))

objdump -D -b binary -m i8086 -M intel $STARTOPT $STOPOPT $IN | sed '1,7d'
