# 添加 .gitignore 文件之后，可能有些文件报错 `ignored tracked with git`

# 部分动态文件可能报错文件内容不一致 `the following files have staged content different from both the file and the HEAD`
# 需要增加 `-f` 参数进行强制删除
$ git rm --cached -f .idea/workspace.xml

Git Cherry-pick

# 指定某一次提交，合并到当前分支中
$ git cherry-pick 5738c801c

如何在代理环境下，同时支持 github / gitlab / coding 的免密操作

场景介绍

  • github.com 和 coding.net 需要走代理访问
  • gitlab 是自建的私服

　在任何 git 相关操作之前，需要先配置 PAC 文件，来保证本机网络的畅通

var proxy = "__PROXY__";

var direct = 'DIRECT;';

var hasOwnProperty = Object.hasOwnProperty;

function FindProxyForURL(url, host) {
    var suffix;
    var pos = host.lastIndexOf('.');
    pos = host.lastIndexOf('.', pos - 1);

            return proxy;
        }
        pos = host.lastIndexOf('.', pos - 1);
    }
}

SSH 配置

　在配置 SSH 之前，同样需要保证 ssh 命令使用的网络代理是正确的

　首先，找到 connect 命令安装路径

$ which connect
  /mingw64/bin/connect

$ which connect.exe
  /mingw64/bin/connect.exe
