Uh, no; 755 *is* executable mode for user/group/world. Something else
has gotten messed up in the file in question. Really, this is so basic:

08:48 /tmp $ cat > example.rb
#!/usr/bin/env ruby

puts "hello"
08:48 /tmp $ ./example.rb
bash: ./example.rb: Permission denied
08:48 /tmp $ ruby ./example.rb
hello
08:48 /tmp $ chmod 755 example.rb
08:48 /tmp $ ./example.rb
hello
08:48 /tmp $

Seriously, you would suggest someone change their *hostname*
just to have different prompt text?

When it can be configured to show actual *useful* information like
the directory you're in or which git branch is checked out?

And to the OP - yes, it's an Ubuntu/shell question, and you should
make time to learn about working in a command-line environment;
it will be effort well-spent.
