$ cat file | nc -l -p 6666

And of course, if you've been following along for a week or two, you know that this (BING!) is a Useless Use of Cat!

Remember, nearly all cases where you have:

cat file | some_command and its args ...

you can rewrite it as:

some_command and its args ... < file

and in some cases, but not this one, you can move the filename to the arglist as in:

some_command and its args ... file

Just another Useless Use of the Internet...
