切换分支
xy@DESKTOP-BG9HNHK MINGW64 ~/Desktop/web/web (branch3)
$ git branch
branch2
* branch3
master
temp
可以看到当前在branch3分支上，那么我们切换到master分支上如
xy@DESKTOP-BG9HNHK MINGW64 ~/Desktop/web/web (branch3)
$ git checkout master
Switched to branch 'master'
Your branch is ahead of 'origin/master' by 1 commit.
(use "git push" to publish your local commits)
xy@DESKTOP-BG9HNHK MINGW64 ~/Desktop/web/web (master)
$ git branch
branch2
branch3
* master
temp
.git/config中文件内容修改也可以达到配置git用户的效果
xy@DESKTOP-BG9HNHK MINGW64 ~/Desktop/web/web (master)
$ git config --local --list

$ git cat-file -t 48142d39abcd7f
commit
这个是查看文件类型的命令，传参时候只需要传递日志id的局部值即可，除非这个局部值有重复则需要改提供为更长长度的局部值。
xy@DESKTOP-BG9HNHK MINGW64 ~/Desktop/web/web (master)
$ git branch -av
branch2 48142d3 modified index.html
branch3 b07d738 modify 2.txt
* master 48142d3 [ahead 1] modified index.html
temp 48142d3 modified index.html
remotes/origin/HEAD -> origin/master
remotes/origin/master b0babbd index
你会发现这里版本列表中master这个分支目前这个日志id也是只取了局部。
接下来看看里程碑

这里有pack目录和如上所示的两个字母的目录，而pack目录中则是对如上面的两个字母的目录的打包。
资源拼接
我们再次查看如上的fb目录
xy@DESKTOP-BG9HNHK MINGW64 ~/Desktop/web/web (branch2)
$ ls -la .git/objects/fb
total 5
drwxr-xr-x 1 xy 197121 0 6月 5 23:37 ./

则我们要看该目录中的某个文件如上面显示的73adb开头的这个文件类型，则如
xy@DESKTOP-BG9HNHK MINGW64 ~/Desktop/web/web (branch2)
$ git cat-file -t fb73adb7a27517731051d98818fa90c721219f33
Tree
也就是用目录名拼接文件名就是完整的日志文件id咯。
另外这个文件是tree文件，所以-p查看内容则就是一个文件列表，即目录内容
xy@DESKTOP-BG9HNHK MINGW64 ~/Desktop/web/web (branch2)
$ git cat-file -p fb73adb7a27517731051d98818fa90c721219f33
100644 blob ed8f593470af4bbe2ae386985dab57c8cb2b5efb app.f73030f9.js
100644 blob e19aed9552148b760f0d9c02844f7ec36e38a784 app.f73030f9.js.map
100644 blob 32c9b76efe5d49620f2ccf42a9be42dda0b612ba chunk-vendors.0396140b.js
100644 blob 8eea8e0372ce00a42304689d52c5780c2c288acb chunk-vendors.0396140b.js.map
那么接下来查看这个app开头的这个blob文件则如
xy@DESKTOP-BG9HNHK MINGW64 ~/Desktop/web/web (branch2)
$ git cat-file -p ed8f593470af4bbe2ae386985dab57c8cb2b5efb
