使用到Process和Runtime两个类，返回值通过Process类的getInputStream()方法获取

package ark; import java.io.BufferedReader;import java.io.IOException;import java.io.InputStreamReader;import java.util.ArrayList;import java.util.List; public class ReadCmdLine { public static void main(String args[]) { Process process = null; List<String> processList = new ArrayList<String>(); try { process = Runtime.getRuntime().exec("ps -aux"); BufferedReader input = new BufferedReader(new InputStreamReader(process.getInputStream())); String line = ""; while ((line = input.readLine()) != null) { processList.add(line); } input.close(); } catch (IOException e) { e.printStackTrace(); } for (String line : processList) { System.out.println(line); } }}

调用shell脚本，判断是否正常执行，如果正常结束，Process的waitFor()方法返回0

public static void callShell(String shellString) { try { Process process = Runtime.getRuntime().exec(shellString); int exitValue = process.waitFor(); if (0 != exitValue) { log.error("call shell failed. error code is :" + exitValue); } } catch (Throwable e) { log.error("call shell failed. " + e); } }

以上这篇java调用shell命令并获取执行结果的示例就是小编分享给大家的全部内容了，希望能给大家一个参考，也希望大家多多支持。
