java를 이용해서 쉘명령어 실행시키는 소스이다.

자세한 설명은 생략!

package com.mungchung.sample;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;

public class ShellCommander {
    public String execute(String command) {
        StringBuffer output = new StringBuffer();
        Process process = null;
        BufferedReader bufferReader = null;
        Runtime runtime = Runtime.getRuntime();
        String osName = System.getProperty("os.name");

        //윈도우일 경우
        if (osName.indexOf("Windows") > -1) {
            command = "cmd /c " + command;
        }

        try {
            process = runtime.exec(command);

            // shell 실행이 정상 동작
            bufferReader = new BufferedReader(new InputStreamReader(process.getInputStream()));
            String msg = null;
            while((msg=bufferReader.readLine()) != null) {

            }
            bufferReader.close();

            // shell 실행시 에러가 발생
            bufferReader = new BufferedReader(new InputStreamReader(process.getErrorStream()));
