Git
關於gitignore是專門用來專案忽略在git上，有些檔案我不想放在 Git 裡面
指令一開始建立.gitignore
$ touch .gitignore
如果跟專案有關，這部分不要忽略，如果非專案可以忽略它
.gitignore
把現有的config忽略
比較常用的C#來說，這些其實在建置C#可以忽略
不必要放置在git裡面

1(.gitignore)的影響範圍是在所在資料夾與子資料夾裡面
2.每個資料夾都可以建置自己(.gitignore)，如果他上層有
(.gitignore)，這個資料夾就會受到它影響
3.(#)開頭代表是註解，(/)代表資料夾路徑，檔案名稱可以用
萬用字元*，(!)代表排除
最近在net core 遇到vs底下編輯，後來還是在.gitignore排除加上這個區塊
.vs/
