Can someone give me a simple example on how to use `Sockets` for that? From the documentation I cannot figure it out.

For example, let us suppose I want to use `grep` to extract some lines from a string (I’m not _actually_ willing to do that, this is just a simple example to illustrate what I want):

```julia-repl
julia> str = """
           abc 
           def
       """
" abc \n def\n"

julia> open("str.txt", "w") do io
           println(io, str)
       end

julia> gr = read(pipeline(`grep "abc" str.txt`), String)
" abc \n"

```

Here, I’m writing to disc an intermediate file `str.txt`. How can avoid that using `Sockets`?
