No, not by the filesystem. And nor should they be. I thought this was the entire point of the conversation. The operating system recognises several magic numbers as signifying executable files. And yes, "#!" is a magic number. On this system it is not in /etc/magic but it is built into the file command and the same goes for ZMAGIC, NMAGIC and OMAGIC. imc
