Stay in the loop…

Follow the Tweets.

Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.

Securely stream (and save) a file from a remote server

Securely stream a file from a remote server (and save it locally).

Useful if you're impatient and want to watch a movie immediately and download it at the same time without using extra bandwidth.

This is an extension of snipertyler's idea.

Note: This command uses an encrypted connection, unlike the original.

Alternatives

There are 5 alternatives - vote for the best!

Terminal - Alternatives
nc HOST PORT | tee movie.mp4 | mplayer -

Requires a listening port on HOST

eg. "cat movie.mp4 | nc -l 1356 " (cat movie.mp4 | nc -l PORT)

Useful if you're impatient and want to watch a movie immediately and download it at the same time without using extra bandwidth.

You can't seek (it'll crash and kill the stream) but you can pause it.

Know a better way?

If you can do better, submit your command here.

What others think

HOST requires USER@HOST for ssh

and HOST PORT for nc.

Thanks. I've edited the command to make it clearer.

By default ssh will use your current username (unless your .ssh/config says otherwise).

Streaming on the LAN via SSH? I'd vote for the SSH variant if you'd reposted it with a more appropriate title: "stream and copy a video from anywhere" or so, or if you are working for Google or such and your LAN is spread out between different data centers... :)
