os 모듈 사용하기

os 모듈은 운영체제의 정보를 얻어오는 매우 유용한 함수 세트를 제공한다.

다음 코드는 os 모듈의 각 함수를 호출한 결과이다.

var os = require('os');
console.log("tmpdir :\t" + os.tmpdir());
console.log("endianness :\t" + os.endianness());
console.log("hostname :\t" + os.hostname());
console.log("type :\t\t" + os.type());
console.log("platform :\t" + os.platform());
console.log("arch :\t\t" + os.arch());
console.log("release :\t" + os.release());
console.log("uptime :\t" + os.uptime());
console.log("loadavg :\t" + os.loadavg());
console.log("totalmem :\t" + os.totalmem());
console.log("freemem :\t" + os.freemem());
console.log("EOL :\t" + os.EOL);
console.log("cpus :\t\t" + JSON.stringify(os.cpus()));
console.log("networkInterfaces : " + JSON.stringify(os.networkInterfaces()));

아래는 출력결과 화면이다.
