shell脚本：利用7z备份git项目

注：无git的方法参见：tar 或 7z 备份项目

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：

1. 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
2. 给两个 sh 脚本可执行权限：

   chmod +x backupProject.sh restoreProject.sh

3. 两个脚本与项目文件夹 PROJECTDIR 在同级目录

使用：

1. 备份：

   ./backupProject.sh

2. 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
$
