使用到Process和Runtime兩個類,傳回值通過Process類的getInputStream()方法擷取 [plain] view plain copy 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); } } }
調用shell指令碼,判斷是否正常執行,如果正常結束,Process的waitFor()方法返回0
[java] view plain copy 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); } }
