I need to test in a shell script if an exe file is a .NET or regular Windows PE executable (without running it).

Use case:

  • associate .exe files with this script in Linux.
  • Launch wine or mono according to the format detected.

The solution i've found by now:

file "runme.exe" | grep -i ".net"
if [ $? == 0 ]; then
    EXEPATH="mono runme.exe"
    EXEPATH="wine runme.exe"
