java调用shell脚本，并得到shell脚本的返回值

文件名确实不对
.sh文件才是linux下的批处理文件，它不认bat的
另外要保证.sh中调用的其他函数在当前目录下能正常运行

用IO截获噻，给你个例子：

public static void main(String[] args) {

String cmd = "pwd";
Runtime run = Runtime.getRuntime();
String result = "";
try {
Process p = run.exec(cmd);
BufferedInputStream in = new BufferedInputStream(p.getInputStream());
BufferedReader br = new BufferedReader(new InputStreamReader(in));
String lineStr;
while ((lineStr = br.readLine()) != null) {
result += lineStr;
}
br.close();
in.close();
} catch (Exception e) {
e.printStackTrace();
}
System.out.println(result);
}
