websocketd

Like inetd, but for WebSockets. Turn any application that uses STDIN/STDOUT into a WebSocket server.

https://github.com/joewalnes/websocketd/wiki

可寫個bash就能把這個bash轉到Websocket上，用Websocket的send()就可以傳給這個bash的STDIN，STDOUT就會傳到Websocket的onmessage(event)裡。

執行時可下參數 --devconsole就會有個console在web上，方便debug

參數--staticdir=web可將web裡的html檔或其他靜態檔讓client存取，不用另外開web server

連接websocket時，可用new WebSocket('ws://' + location.host + '/');
