Git如何获取帮助（命令解释/命令详情）？

1、问题--如何获取git帮助？

2、贴心的git--总是在你需要时出现！

（1）当你输错命令，它会给出建设性意见，很是贴心！就比如这样：

（2）其次，其实我们直接输入git，就会输出相关命令。就像下面这样：

（3）有上面第三行可以看到：'git help -a' and 'git help -g'，试试呗！

3、万能的git，想要啥都能出来！

（1）我们先来看看官网的介绍的几种方法：

（2）简单分析：

（3）演示一下： git status --help

因为复制了比较多命令，比较占篇幅，一开始可以通过文章右边的“目录”栏选看主要内容，后面再研究这些命令。

1、问题--如何获取git帮助？

使用git的过程中，经常会遇到命令打错，或者是参数弄错的情况，那有什么办法可以查看git帮助吗？

2、贴心的git--总是在你需要时出现！

（1）当你输错命令，它会给出建设性意见，很是贴心！就比如这样：

$ git statu
git: 'statu' is not a git command. See 'git --help'.The most similar commands arestatusstagestash

（2）其次，其实我们直接输入git，就会输出相关命令。就像下面这样：

$ git

3、万能的git，想要啥都能出来！

（1）我们先来看看官网的介绍的几种方法：

若你使用 Git 时需要获取帮助，有三种方法可以找到 Git 命令的使用手册：
$ git help <verb>
$ git <verb> --help
$ man git-<verb>
这些命令很棒，因为你随时随地可以使用而无需联网。

转自：git官网

前两种都可以在Windows和Linux的git中使用，第三种man是Linux的。（我比较常用的是第二种，命令后面直接求帮助。）

（2）简单分析：

前两种命令的作用都是一样的：打开本地的离线文档（网页），我的文件文件地址是： file:///G:/Git/mingw64/share/doc/git-doc/，即在安装git的目录下的对应文件夹中，用命令直接打开。

（3）演示一下： git status --help

看完这篇博客你还怕找不到git说明吗？

划重点：文档是全英文的，如果英语不过关，一开始建议弄个翻译软件，中英换着看，不要一直看中文的，因为有些内容翻译和实际意思会有很大偏差的。习惯了，看英语就很流畅了。
