### 4.2 检查更新
如果从仓库版本安装了OpenFOAM，则更新非常简单。要更新OpenFOAM时，只需使用Git来检查是否有更新的源文件。在终端中切换到OpenFOAM安装的根目录，然后执行git pull。

如果仓库中有较新的文件，Git会下载它们并显示已更改文件的摘要。如列表10所示。
```
user@host :∼$ cd $FOAM_INST_DIR
user@host :∼/ OpenFOAM$ cd OpenFOAM -2.1. x
user@host :∼/ OpenFOAM / OpenFOAM -2.1. x$ git pull
remote : Counting objects : 67 , done .
