shell脚本：利用7z备份git项目

首先利用homebrew安装p7zip

$ brew install p7zip

然后利用两个shell脚本：

backupProject.sh 会在指定的项目文件夹中找到所有.git目录，对其git gc压缩，然后用7za创建两个7z文件：
- PROJECTDIR.2016-03-15-12-00-00.Src.7z
- PROJECTDIR.2016-03-15-12-00-00.gitpack.7z
restoreProject.sh 会将上述两个文件用7za解压到目录：
- PROJECTDIR.2016-03-15-12-00-00.output

准备：

准备工作：首先用文本编辑工具打开 backupProject.sh 文件，修改项目名称 projPath=PROJECTDIR 和压缩密码 password=Demo 然后打开 restoreProject.sh 文件，修改解压缩密码 password=Demo

给两个 sh 脚本可执行权限：

chmod +x backupProject.sh restoreProject.sh

两个脚本与项目文件夹 PROJECTDIR 在同级目录

使用：

备份：
```
./backupProject.sh
```

还原：

./restoreProject PROJECTDIR.-----.Src.7z

例子：

$ ls

PROJECTDIR        backupProject.sh        restoreProject.sh

// 备份

$ ./backupProject.sh

Ready...

git gc: PROJECTDIR/.git

Nothing new to pack.

git gc: PROJECTDIR/frameworks/.git

...

git gc: PROJECTDIR/library/.git

...

git gc: PROJECTDIR/Universal/.git

...

Backuping(/): PROJECTDIR.-----.Src.7z

...

Backuping(/): PROJECTDIR.-----.gitpack.7z

...

Done.

$ ls

PROJECTDIR

PROJECTDIR.-----.Src.7z

PROJECTDIR.-----.gitpack.7z

backupProject.sh

restoreProject.sh

// 恢复

$ ./restoreProject.sh PROJECTDIR.-----.Src.7z

Ready...

Extracting PROJECTDIR.-----.Src.7z...

...

Extracting PROJECTDIR.-----.gitpack.7z...

...

Output Dir: PROJECTDIR.-----.output

Done.

$ ls

PROJECTDIR

PROJECTDIR.-----.Src.7z

PROJECTDIR.-----.output

PROJECTDIR.-----.gitpack.7z

backupProject.sh

restoreProject.sh

$ ls PROJECTDIR.-----.output/

PROJECTDIR

$

脚本源码如下：
