Node.js的os module 提供了一系列跟操作系統相關的操作函數，比較簡單，所以功能也就十分有限。我們可以去官網看各個函數的介紹：

2 var os = require('os'); 3 4 console.log('the os tmpdir is: ' + os.tmpdir()); 5 console.log('the endianness of this os is: ' + os.endianness()); 6 console.log('the hostname of this os is: ' + os.hostname()); 7 console.log('the type of this os is: ' + os.type()); 8 console.log('the platform of this os is: ' + os.platform()); 9 console.log('the arch of this os is: ' + os.arch()); 10 console.log('the release of the os is: ' + os.release()); 11 console.log('the uptime os the os is: ' + os.uptime()); 12 13 14 console.log('the end of line of this os is: ' + os.EOL); //os.EOL：操作系統的換行符 15 console.log('................................................'); 16 console.log('................................................'); 17 showObj(os.cpus()); 18 console.log('................................................'); 19 console.log('................................................'); 20 showObj(os.networkInterfaces()); 21 console.log('................................................'); 22 console.log('................................................'); 23 showObj(os.loadavg()); 24 25 26 27 28 function showObj(obj){ 29 if (obj == null) { 30 console.log('error: ' + obj); 31 return false; 32 } 33 for (var key in obj) { 34 //key is a string, so we cannot use obj.key to replace obj[key] at here. For example, if name is a property of obj:
//(obj.name is right, but obj."name" is wrong.)
//(obj["name"] is right, but obj[name] is wrong.)
35 if (typeof(obj[key]) == 'array' || typeof(obj[key]) == 'object') { 36 showObj(obj[key]); 37 } else { 38 if (obj[key] != null) 39 console.log(key + "=" + obj[key]); 40 } 41 } 42 } 43
