Check if a windows binary (.exe) was compiled for 32 Bit or 64 Bit (useful for wine)

README.md

About

This script checks whether a windows binary (.exe file) was compiled ro 32 Bit or 64 Bit. If you mess around with Wine / PlayOnLinux a lot, this could be useful.

Usage

Making the script executable

chmod +x ./bincheck.sh

Using the Sript:

./bincheck.sh ./path/to/binary.exe

bincheck.sh

#!/bin/bash

if [[ $# -eq 0 ]]; then
    echo "No file provided"
    exit 1
fi

DATA=$(head "$1" | tr -d '\0')

echo "$DATA" | grep -E '(PE)(\s*)(L)' >> /dev/null
LOBIT=$?

echo "$DATA" | grep -E '(PE)(\s*)(d†)' >> /dev/null
HIBIT=$?

if [[ "$LOBIT" == 0 ]]; then
    echo "This Binary is 32 Bit"
    exit 0
elif [[ "$HIBIT" == 0 ]]; then
    echo "This Binary is 64 Bit"
    exit 0
else
    echo "Couldn't determine wordlength"
    exit 1
fi
