Linux/Unix 桌面趣事:蒸汽火车
================================================================================
一个[最常见的错误][1]是把ls输入成了sl。我已经设置了[一个alias][2]也就是alias sl=ls。但是你也许就错过了带汽笛的蒸汽小火车了。
sl是一个玩笑软件或是一个Unix游戏。它会在你错误地把“ls”输入成“sl”Steam Locomotive后出现一辆蒸汽火车穿过你的屏幕。
### 安装 sl ###
在Debian/Ubuntu下输入下面的命令
# apt-get install sl
它同样也在Freebsd和其他类Unix的操作系统上存在。下面把ls输错成sl
$ sl
![Fig.01: Run steam locomotive across the screen if you type "sl" instead of "ls"](http://files.cyberciti.biz/uploads/tips/2011/05/sl_command_steam_locomotive.png)
图01: 如果你把“ls”输入成“sl”蒸汽火车会穿过你的屏幕。
It also supports the following options:
它同样支持下面的选项:
- **-a** : 似乎发生了意外。你会哭喊求助的人们感到难过。
- **-l** : 显示小一点的火车
- **-F** : 它飞走
- **-e** : 允许被Ctrl+C终端
