git commit的时候，刷新css中的资源：图片什么的。如：如果提交发现对anywhere/header.png有更改，那么搜索包含header.png的css文件，然后匹配css中的header.png是否为同一个文件，如果是：加上时间戳以更新缓存。 未完：更改文件后无法加入本次commit。待解决
#!/bin/sh
#刷新css中的资源：图片什么的
#检查流程：
# 1. 检查变更的资源文件 git status -s
# 2. 将取得的文件名在所有css文件中进行搜索
# 3. 在匹配的css中取得符合的资源相对路径
# 4. 检查相对路径指向的是否为目标文件
# 5. 更新匹配的相对路径的时间戳为当前时间
