Java 调用Linux 命令，并获取命令执行结果

1.工具类

[code]public class ExcuteLinux {

public static String exeCmd(String commandStr) {

String result = null;
try {
String[] cmd = new String[]{"/bin/sh", "-c",commandStr};
Process ps = Runtime.getRuntime().exec(cmd);

BufferedReader br = new BufferedReader(new InputStreamReader(ps.getInputStream()));
StringBuffer sb = new StringBuffer();
String line;
while ((line = br.readLine()) != null) {
//执行结果加上回车
sb.append(line).append("\n");
}
result = sb.toString();

} catch (Exception e) {
e.printStackTrace();
}

return result;

}
}

2.调用

[code]public class main {

public static void main(String[] args) {
String result = ExcuteLinux.exeCmd("ifconfig");
System.out.println("获取的结果是"+"\n"+result);

}
}

3.Linux 上执行jar包显示结果
