Subject: [ruby-core:32745] ruby requires shebang for executable files?

Hi all.  I've noted that ruby typically tries to follow "bash like"
semantics for executing files, like
system("ls && ls") works like bash does.

However, I've also noticed that if I set a file to executable but do
not have a shebang, it does nothing--is this expected?
Thanks.
