安装和使用 Git 版本管理系统
Super Quick Git Guide: Generally about contributing to pacman, although it still serves as a practical Git tutorial
Concurrent Versions System

Git 是一个 Linus Torvalds 编写的版本控制系统 (VCS),现在被用来维护 Linux 内核以及数以千计的其他项目,包括 Pacman(Arch 的软件包管理器)

有一个很全面的文档,包含了手册和教程,可以从 官方网站 获得。


git 可以用 Pacman 从 [extra] 仓库安装。如果你关心使用 Git 配合其他的 VCS 软件,邮件服务器,或者使用 Git 的图形界面,注意看可选的依赖。

Bash 自动完成 (例如,按 tab 来完成你正在键入的命令),只需要:

source /usr/share/git/completion/git-completion.bash

另外,你可以安装 bash-completion 软件包来自动为新的外壳加载自动完成。

如果你想使用 Git 内建的图形界面 (例如 gitk 或者 git gui) 你需要安装 tk 软件包,否则你会遇到一个隐晦的错误信息:

/usr/bin/gitk: line 3: exec: wish: not found.


Git 从几个 INI 格式的配置文件中读取配置信息。在每一个 git 仓库中 .git/config 被用来指定与本仓库有关的配置选项。每一个用户 ("global") 的配置文件在 $HOME/.gitconfig 被用来作为仓库配置的备用配置。你也可以直接编辑文件,但是更推荐的方法是使用 git-config 工具。例如,

$ git config --global core.editor "nano -w"

会添加 editor = nano -w~/.gitconfig 文件的 [core] 部分中。

git-config 工具的 man page 有一个很长的参数列表,列出所以可以设置的变量。


$ git config --global user.name "Firstname Lastname"
$ git config --global user.email "your_email@youremail.com"
$ git config --global color.ui true
$ git config --global --list


内容来自很多地方,很多来自这个不错的教程 http://schacon.github.com/git/gittutorial.html

另外可以参考 Super Quick Git Guide.

Pull 网络脚本,用以下命令:

git clone http://archlinux.org/~james/projects/network.git


git pull origin


git commit -a -m "changelog message"


git branch somebranch


git checkout differentbranch


git merge somebranch


git branch -d somebranch

Push a local branch or tag to a remote repository





git diff master..somebranch

两个提交ID(可以在 git 日志找到)比较

git diff e9780c7cba2855350e914fde227a79bb63c1351d..8b014e40346b38b3b9bfc41359b4e8a68e804c0d


git diff HEAD^ HEAD

两个分支之间制作补丁 (follows same syntax as git diff afaik)

git format-patch master..somebranch

或者更好的办法: http://wiki.winehq.org/GitWine#head-f7a29e7ed999b5924748a60c5a1cd4a019032d26

git format-patch -o out origin

设置 nano 为默认编辑器

git config --global core.editor "nano -w"

Git Prompt

Git package comes with a bash completion file. This file, also contains the necessary functions to provide git information on your bash or zsh shell prompt. To enable it add $(__git_ps1 " (%s)") to you PS1 variable.

  • For bash:
PS1='[\u@\h \W$(__git_ps1 " (%s)")]\$ '
  • For zsh:
PS1='[%n@%m %c$(__git_ps1 " (%s)")]\$ '

The %s is replaced by the current branch name. The git information is displayed only if you are navigating in a git repository. You can enable extra information by setting and exporting certain variables to a non-empty value as shown in the following table:

Variable Information
GIT_PS1_SHOWDIRTYSTATE * for unstaged and + for staged changes
GIT_PS1_SHOWSTASHSTATE $ if something is stashed
GIT_PS1_SHOWUNTRACKEDFILES % if there are untracked files

In addition you can set the GIT_PS1_SHOWUPSTREAM variable to "auto" in order to see < if you are behind upstream, > if you are ahead and <> if you have diverged.

Note: If you don't use bash completion consider sourcing /usr/share/git/completion/git-completion.bash in your .bashrc/.zshrc

Transfer Protocols

Smart HTTP

Since version 1.6.6 git is able to use the HTTP(S) protocol as efficiently as SSH or GIT by utilizing the git-http-backend. Furthermore it is not only possible to clone or pull from repositories, but also to push into repositories over HTTP(S).

The setup for this is rather simple as all you need to have installed is the Apache webserver (with mod_cgi, mod_alias, and mod_env enabled) and of course, git:

# pacman -S apache git

Once you have your basic setup up and running, add the following to your Apache's config usually located at /etc/httpd/conf/httpd.conf:

<Directory "/usr/lib/git-core*">
    Order allow,deny
    Allow from all

SetEnv GIT_PROJECT_ROOT /srv/git
ScriptAlias /git/ /usr/lib/git-core/git-http-backend/

The above example config assumes that your git repositories are located at /srv/git and that you want to access them via something like http(s)://your_address.tld/git/your_repo.git. Feel free to customize this to your needs.

Note: Of course you have to make sure that your Apache can read and write (if you want to enable push access) on your git repositories.

For more detailed documentation, visit the following links:


You first need to have a public SSH key. For that follow the guide at Using SSH Keys. To setup SSH itself you need to follow the SSH guide. I assume you have a public SSH key now and your SSH is working. Open your SSH key in your favorite editor (default public key name is id_rsa.pub and is located in ~/.ssh) and copy its content (CTRL + C). Now go to your user where you have made your git repository, since we now need to allow that SSH key to login on that user to access the GIT repository. Open this file in your favorite editor (i use nano)

nano ~/.ssh/authorized_keys

and paste the contents of id_rsa.pub in it. Be sure it is all on one line! That is important! It should look somewhat like this:

Warning: Do not copy the line below! It is an example! It will not work if you use that line!
ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAAAgQCboOH6AotCh4OcwJgsB4AtXzDo9Gzhl+BAHuEvnDRHNSYIURqGN4CrP+b5Bx/iLrRFOBv58TcZz1jyJ2PaGwT74kvVOe9JCCdgw4nSMBV44cy+6cTJiv6f1tw8pHRS2H6nHC9SCSAWkMX4rpiSQ0wkhjug+GtBWOXDaotIzrFwLw== username@hostname

Now you can checkout your git repo this way (change where needed. Here it is using the git username and localhost):

git clone git@localhost:my_repository.git

You should now get an SSH yes/no question. Type yes followed by enter. Then you should have your repository checked out. Since this is with SSH you also do have commit rights now. For that look at Git and Super Quick Git Guide.

Specifying a non-standard port

Connecting on a port other than 22 can be configured on a per-host basis in /etc/ssh/ssh_config or ~/.ssh/config. To set up ports for a repository, specify the path in .git/config using the port number N and the absolute path /PATH/TO/REPO:


Typically the repository resides in the home directory of the user which allows you to use tilde-expansion. Thus to connect on port N=443,

url = git@example.org:repo.git


url = ssh://git@example.org:443/~git/repo.git

GIT Daemon

Note: The git daemon only allows read access. For write access see #Git SSH.

This will allow URLs like "git clone git://localhost/my_repository.git".

Edit configuration file for git-dameon /etc/conf.d/git-daemon.conf (GIT_REPO is a place with your git projects), then start git-daemon with root privileges:

# /etc/rc.d/git-daemon start

To run the git-daemon every time at boot, just append git-daemon to DAEMONS line in rc.conf.

Clients can now simply use:

git clone git://localhost/my_repository.git

GIT repositories rights

To restrict read/write access, you can simply use Unix rights, see http://sitaramc.github.com/gitolite/doc/overkill.html
