Git忽略提交规则

2019年07月29日  | 移动技术网IT编程  | 我要评论

现在开源项目越来越多，git使用越来越方便，用git的人也越来越多。创建项目的时候，喜欢把日志，临时文件，项目编译的中间文件，引用的类库等等，这时就要设置响应的规则，来忽略这些文件。例如创建一个c#项目，项目下面会有.vs，bin，obj等，这些都是不需要提交的需要忽略的，如何忽略呢？其实很简单，增加.gitignore文件就可以了，下面将详细说明c#项目的忽视规则。

创建git项目

创建git项目，创建的时候有个.gitignore的选项，根据自己的需要选择需要忽视的文件，例如：java，python等，c#的项目选择visualstudio，因为创建的都是vs项目，这里面有需要c#项目所忽略的设置。创建完项目之后，项目下面就有个.gitignore文件，这个文件是可以修改的。

忽视文件

例如：忽视后缀是.suo，.user的文件，*正式所有

*.suo
*.user

忽视文件夹

[dd]用的是正则，匹配大小写d，两个**表示匹配任意中间目录

[dd]ebug/
[dd]ebugpublic/
[rr]elease/
[rr]eleases/
**/[pp]ackages/*

git忽略文件的原则

1. 编译生成的文件，例如：dll，等
2. 配置文件，敏感的信息（密码，口令）
3. 项目工具生成的文件，例如：引用nuget时生成的packages等
4. 项目测试的文件，日志文件等。

.gitignore忽略规则的匹配语法

1. “#"开头，是git上的注释说明
2. 以"/"开头表示根目录，其他位置的“/”表示的是忽视目录
3.“*”匹配多个字符，“**”匹配任意中间目录
4.“[]”匹配中括号中的字符
5.“!”表示不忽视,即：如果忽视某些文件，可以用!让这些文件在启用，如果文件夹的父目录被忽略了，那么这个文件在启用，也就没有什么用了。
注意：git对于.ignore配置文件是从上到下进行规则匹配的，如果前面的规则匹配的范围更大，则后面的规则将不会生效；git上的忽视文件.ignore要在创建git的时候创建，如果是之后创建的，已经push过的，在忽视将不起作用，因为git已经开始管理这些文件了。

.gitignore查看忽视文件和文件夹

 git check-ignore -v bin
 .gitignore:23:[bb]in/   bin

查看忽视文件夹，可以看到，第23行的忽视规则把bin给忽视掉了，如果运行指令，没有返回值则表示没有忽视此文件或者文件夹的规则。

git忽视已经上传的文件解决办法

在使用git的时候，创建了一个.gitignore文件，但是后来发现有一个文件已经上传了，没有写忽视规则，但是又想这个文件【本地保存】，【远程删除】，例如：忽视已经上传的文件【test.txt】或者文件夹，用git rm -r –cached directory
1. git rm -r --cached test.txt
2. commit和push
操作之后，你可以看到本地文件还在，远程的已经删除了

vs项目忽视文件（c#、.net，mvc等）
