用JAVA查看Linux的进程情况，并获取PID
//判断本地进程状态

//command为要查看的进程的启动命令，若存在可获得PID，然后可以执行KILL以便杀掉，呵呵。command也可以为其他Linux上的执行命令，但就不是查看进程了，可以改造为查看命令执行结果（在while处更改）
public static boolean SoftStatus(String command){
boolean re=false;
try{
command="ps -ef";
Process child = Runtime.getRuntime().exec(command);
BufferedReader ins = new BufferedReader(new InputStreamReader(child.getInputStream()));
String c=null;
while ((c = ins.readLine()) != null) {
//System.out.println("PID:"+c.substring(10,14));
if(c.indexOf(command)>0) System.out.println(c);
}
ins.close();

if(c.indexOf(command)>0) System.out.println(c);
