echo 指令 输出重定向 追加重定向 管道 先touch 出一个文件 file.txt ,然后通过shell脚本在里面创造10万行 “hello 100 Linux $count” 语句 如果此时输入 cat file.txt ,那么显示器上就会从第一行一直打印到第十万行,光是显示完这10万行语句都要花很长时间,更别说翻看了。而且它一直在刷屏,换言之,你想看...

基本上所有的网络应用都会示范一个tcp的echo写法。前面我们已经看到了如何使用协程和异步io来做tcp服务器的第一步,accept。下面是一个完整的echo server的实现(完整代码): package org.github.taowen.daili; import kilim.Pausable; import java.net.InetSocketAddress; ...
In the last chapter, you learned the basics of the WORKSPACE file, learning how to add external dependencies, including new languages. In this chapter, we are going to build off of that work to create a simple pair of programs, in different languages (one in Java, the other in Go), ...
下面是一个java写的echo server。基于NIO2的callback和Quasar的fiber,比mina和netty之流好看实在太多了。而且同样是异步IO实现的,应该性能不差的。 package echo_server; import co.paralleluniverse.fibers.*; import co.paralleluniverse.fibers.io.*; import java.io.IOException; ...
不依赖三方库,使用Java Socket实现WebSocket Server,完整代码放在github: https://github.com/martin2038/example-ws 整体来看,WebSocket比Socket还是更高层一点,但也没有包装太多。 总结 本质上就是一个Socket,不过可以跟HTTP共用一个大门(80/443端口,便于穿透各种防火墙); ...
This article is a tutorial on implementing a simple Java NIO “echo server”. This example will take the form of a rather simple client server application whereby a client or many clients will connect to a running server and post message(s) to the server which will in turn be “echoed”...
technology is employed to deliver a user experience to web clients that approaches that of traditional desktop applications. Echo applications can be created entirely in server-side Java code using a component-oriented and event-driven API or as client-side applications written entirely in JavaScript....
