Bad test on my part, apparently.
$ python
import os os.execv('/home/gmessmer/test', ('test',))
Traceback (most recent call last): File "<stdin>", line 1, in <module> OSError: [Errno 8] Exec format error
So a script with no shebang will fail when the shell calls exec(). If that's so, then starting the executable script with an interpreter is probably shell-defined. In other words, each shell might do something different to run a script that has no shebang. Most probably do default to trying itself as the interpreter first. Interesting.
is file test chmod +x ?
