1、配置語法：
以斜杠“/”開頭表示目錄；
以星號“*”通配多個字符；
以問號“?”通配單個字符
以方括號“[]”包含單個字符的匹配列表；
以嘆號“!”表示不忽略(跟蹤)匹配到的文件或目錄；
此外，git 對於 .ignore 配置文件是按行從上到下進行規則匹配的，意味着如果前面的規則匹配的范圍更大，則后面的規則將不會生效；
2、示例：
（1）規則：fd1/*
說明：忽略目錄 fd1 下的全部內容；注意，不管是根目錄下的 /fd1/ 目錄，還是某個子目錄 /child/fd1/ 目錄，都會被忽略；
（2）規則：/fd1/*
說明：忽略根目錄下的 /fd1/ 目錄的全部內容；
（3）規則：
/*
!.gitignore
!/fw/bin/
!/fw/sf/
說明：忽略全部內容，但是不忽略 .gitignore 文件、根目錄下的 /fw/bin/ 和 /fw/sf/ 目錄；
這里給出一個Visual Studio 的igitignor實例供大家參考。
