从主仓库更新代码到 fork 仓库

shell
git remote -v
git remote add github https://github.com/chenxiangfang/Main.git
git fetch github
git merge github/master
git push

从 github 中拉取变更同步到本地，并提交到 fork 仓库

shell
git fetch github
git merge github/master
git push
git fetch github --all
git push origin --all

配置 Git 提交时的邮箱和用户名

shell
# 全局修改
git config --global user.email "XXX@XXX.com"
git config --global user.name "cainiao"
# 当前仓库修改
git config user.email "XXX@XXX.com"
git config user.name "cainiao"

设置 HTTP/HTTPS 免密登录（git clone 第二次不需要再次输入密码了）

bash
# Windows
git config --global credential.helper wincred
# macOS
git config --global credential.helper osxkeychain

设置 HTTP 代理

bash
# 设置代理
git config --global http.proxy http://proxyUsername:proxyPassword@proxy.server.com:port
git config --global https.proxy https://proxyUsername:proxyPassword@proxy.server.com:port

# 取消代理
git config --global --unset http.proxy

线上Git仓库把 master 主分支改为了 main 主分支

bash
# Switch to the "master" branch:
git checkout master

# Rename it to "main":
git branch -m master main

# Get the latest commits (and branches!) from the remote:
git fetch

# Remove the existing tracking connection with "origin/master":
git branch --unset-upstream

# Create a new tracking connection with the new "origin/main" branch:
git branch -u origin/main

我的一些全局 Git 配置

shell
git config --global http.proxy socks5://127.0.0.1:1080
git config --global https.proxy socks5://127.0.0.1:1080

git config --global user.email "565499699@qq.com"
git config --global user.name "Xiangfang Chen"

git config --global core.autocrlf false
git config --global core.filemode false
git config --global core.preloadindex true
git config --global core.fscache true
git config --global branch.autosetuprebase always
git config --global core.longpaths true

一些错误的解决方案

Git command returns fatal error: "detected dubious ownership" fatal: unsafe repository(XXXX is owned by someone else.)

shell
# windows:
takeown /r /d y /f <PATH>
# linux:
chown -R username:group <PATH>

# 或者忽略全部文件夹
git config --global --add safe.directory "*"

Filename too long.

shell
git config --global core.longpaths true
