Command example

This example connects a websocket connection to stdin and stdout of a command. Received messages are written to stdin followed by a \n. Each line read from from standard out is sent as a message to the client.

$ go get github.com/gorilla/websocket
$ cd `go list -f '{{.Dir}}' github.com/gorilla/websocket/examples/command`
$ go run main.go <command and arguments to run>
# Open http://localhost:8080/ .

Try the following commands.

# Echo sent messages to the output area.
$ go run main.go cat

# Run a shell.Try sending "ls" and "cat main.go".
$ go run main.go sh
