git - doubility-sky/daydayup Wiki

Git is a free and open source distributed version control system designed to handle everything from small to very large projects with speed and efficiency.

Git is easy to learn and has a tiny footprint with lightning fast performance. It outclasses SCM tools like Subversion, CVS, Perforce, and ClearCase with features like cheap local branching, convenient staging areas, and multiple workflows.

GUI Clients

Git comes with built-in GUI tools for committing (git-gui) and browsing (gitk), but there are several third-party tools for users looking for platform-specific experience.

  • :star:Fork for Windows and Mac
  • Sourcetree: A free Git client for Windows and Mac
  • GitKraken: Legendary Git client for Windows, Mac & Linux. Free for open source
  • lazygit: simple terminal UI for git commands

    • A 换行符问题 - Git权威指南
      • 不要手动去设置 core.autocrlf,默认即可(linux,macosxfalse, wintrue)
      • 设置: git config --global core.safecrlf true
      • 特别需求添加 .gitattributes 去约束

  • gitlab fetch/pull 失败
  • 解决冲突出错
    • git reset --hard 无效
      fatal: Unable to create '/.git/index.lock': File exists.
      If no other git process is currently running, this probably means a
      git process crashed in this repository earlier. Make sure no other git
      process is running and remove the file manually to continue.
    • How do I fix a failed git commit?
      Removing index.lock file manually from .git directory worked.
