Re: Re: sed "Hello, world!" program?

Agree.

If echo I would rather go for

sed ...<<<"hello world"

I think this is my favorite so far. It should be cross-platform with

the following benefits:

- no trouble escaping the "!"

- no trouble with single-vs-double quotes

- no need for a specific external utility (though "echo" still has

fairly broad support) as long as you have *something* that produces

output on stdout, including any arbitrary text file

- no dependency on redirecting-stderr notation

- demonstrates that sed scripts can be external files, not just the

command command-line usage

- demonstrates use of the archetypal s/// command

So I'm +1 on this.
