如何在java程序中调用linux命令或者shell脚本

Answer 1

**
* 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;
}
