Java调用shell脚本并获得结果

Java代码

1. /**
2. *运行shell脚本
3. *@paramshell需要运行的shell脚本
4. */
5. publicstaticvoidexecShell(Stringshell){
6. try{
7. Runtimert=Runtime.getRuntime();
8. rt.exec(shell);
9. }catch(Exceptione){
10. e.printStackTrace();
11. }
12. }
15. /**
16. *运行shell
17. *
18. *@paramshStr
19. *需要执行的shell
20. *@return
21. *@throwsIOException
22. */
23. publicstaticListrunShell(StringshStr)throwsException{
24. List<String>strList=newArrayList();
26. Processprocess;
27. process=Runtime.getRuntime().exec(newString[]{"/bin/sh","-c",shStr},null,null);
28. InputStreamReaderir=newInputStreamReader(process
29. .getInputStream());
30. LineNumberReaderinput=newLineNumberReader(ir);
31. Stringline;
32. process.waitFor();
33. while((line=input.readLine())!=null){
34. strList.add(line);
35. }
37. returnstrList;
38. }

/**
	 * 运行shell脚本
	 * @param shell 需要运行的shell脚本
	 */
	public static void execShell(String shell){
		try {
			Runtime rt = Runtime.getRuntime();
			rt.exec(shell);
		} catch (Exception e) {
			e.printStackTrace();
		}
	}


/**
	 * 运行shell
	 * 
	 * @param shStr
	 *            需要执行的shell
	 * @return
	 * @throws IOException
	 */
	public static List runShell(String shStr) throws Exception {
		List<String> strList = new ArrayList();

		Process process;
		process = Runtime.getRuntime().exec(new String[]{"/bin/sh","-c",shStr},null,null);
		InputStreamReader ir = new InputStreamReader(process
				.getInputStream());
		LineNumberReader input = new LineNumberReader(ir);
		String line;
		process.waitFor();
		while ((line = input.readLine()) != null){
		    strList.add(line);
		}
		
		return strList;
	}

注:如果sh中含有awk,一定要按new String[]{"/bin/sh","-c",shStr}写,才可以获得流
