Most programming languages have a "Hello, world!" example. Some might debate if sed is a "real" programming language. But sed at least resembles a programming language in many ways. Anyway, assuming sed is a programming language, what might be sed "Hello, world!" program?
I think the criteria are: **** Prints "Hello, world!". *** Is one of the simplest programs in the language (opposite of an obfuscation contest). *** Can be useful to demonstrate the language.
http://en.wikipedia.org/wiki/List_of_Hello_world_program_examples http://en.wikipedia.org/wiki/List_of_Hello_world_program_examples shows "Hello, world!" programs for various languages...
Perhaps this is a silly post. Or maybe it might interest someone, or make us think more about how sed works. I don't offer any suggestions at this point, am thinking about an answer.
