Subject: [ruby-core:82276] [Ruby trunk Bug#13786] Unexpected behavior	handling shebang

Issue #13786 has been updated by nobu (Nobuyoshi Nakada).


Ruby tries to parse options after "ruby" in a shebang line, and assumes there are only options.
So the last "ruby" is treated as "-ruby" option.

----------------------------------------
Ruby exhibits unexpected behavior handling this shebang:

~~~
$ cat <<EOF > foo
> #!/usr/bin/scl enable rh-ruby22 -- ruby
> EOF

$ ruby foo
/usr/share/rubygems/rubygems/core_ext/kernel_require.rb:55:in `require': cannot load such file -- uby (LoadError)
	from /usr/share/rubygems/rubygems/core_ext/kernel_require.rb:55:in `require'
~~~
