open C# scripts on Linux in native monodevelop

Once you install your Unity on Linux:

• save this script as unity3d_native_monodevelop.sh

• this is a bash script, give it execution permission with chmod +x unity3d_native_monodevelop.sh

• open Unity and go to Edit>Preferences>ExternalEditor and select this script

• put "$(File)" $(Line) as parameters

That's it!
