想在 server 上持續性地跑個簡單的 script

screen


進到 screen

```sh
screen
```

Detach (離開 screen, 但是讓 screen 裡面的東西繼續執行)

```
ctrl+a d
```


Re-attach (重回 screen)


```sh
screen -r
```

如果有多個就先 screen -ls 找到 screen id 然後 `screen -r screen_id`, ex:

```sh
pungki@mint ~ $ screen -ls
There are screens on:
7849.pts-0.mint (10/06/2013 01:50:45 PM)        (Detached)
5561.pts-0.mint (10/06/2013 11:12:05 AM)        (Detached)
2 Sockets in /var/run/screen/S-pungki
```

```sh
pungki@mint ~ $ screen -r 7849
```
