How to configure git bash command line completion?
提问by Vincent Scheib
E.g. on a fresh ubuntu machine, I've just run sudo apt-get git, and there's no completion when typing e.g. git check[tab].
例如，在新的 ubuntu 机器上，我刚刚运行了sudo apt-get git，并且在输入 eg 时没有完成git check[tab]。
I didn't find anything on http://git-scm.com/docs, but IIRC completion is included in the git package these days and I just need the right entry in my bashrc.
我在http://git-scm.com/docs上没有找到任何东西，但是现在 git 包中包含了 IIRC 完成，我只需要在我的 bashrc 中输入正确的条目。

on most distributions, git completion script is installed into /etc/bash_completion.d/(or /usr/share/bash-completion/completions/git) when you install git, no need to go to github. You just need to use it - add this line to your .bashrc:
在大多数发行版中，当您安装 git 时，git 完成脚本已安装到/etc/bash_completion.d/(或/usr/share/bash-completion/completions/git) 中，无需转到 github。您只需要使用它 - 将此行添加到您的.bashrc：
source /etc/bash_completion.d/git
# or
source /usr/share/bash-completion/completions/git
In some versions of Ubuntu, git autocomplete may be broken by default, reinstalling by running this command should fix it:
在某些版本的 Ubuntu 中，默认情况下 git autocomplete 可能已损坏，通过运行此命令重新安装应该可以修复它：
sudo apt-get install git-core bash-completion
On Mac
在 Mac 上
You can install git completion using Homebrew or MacPorts.

if $BASH_VERSION> 4: brew install bash-completion@2(updated version)
Pay special care which version of bash you have as MacOS default ships with 3.2.57(1)-release.
if $BASH_VERSION> 4：（brew install bash-completion@2更新版本）请特别注意您拥有的 bash 版本，因为 MacOS 默认随 3.2.57(1)-release 一起提供。
add to .bash_profile:
添加到.bash_profile：
if [ -f /usr/local/share/bash-completion/bash_completion ]; then
. /usr/local/share/bash-completion/bash_completion
fi
For older versions of bash: brew install bash-completion
对于旧版本的 bash： brew install bash-completion
add to .bash_profile:
添加到.bash_profile：
[ -f /usr/local/etc/bash_completion ] && . /usr/local/etc/bash_completion
MacPorts
端口
sudo port install git +bash_completion
sudo port install git +bash_completion
then add this to your .bash_profile:
然后将此添加到您的.bash_profile：
if [ -f /usr/share/bash-completion/bash_completion ]; then
. /usr/share/bash-completion/bash_completion
fi

Note that in all cases you need to create a new shell (open a new terminal tab/window) for changes to take effect.
请注意，在所有情况下，您都需要创建一个新的 shell（打开一个新的终端选项卡/窗口）才能使更改生效。

then add the following lines to your .bash_profile(generally under your home folder)
然后将以下行添加到您的.bash_profile（通常在您的主文件夹下）

Most of the instructions you see will tell you to download
您看到的大部分说明都会告诉您下载
https://raw.githubusercontent.com/git/git/master/contrib/completion/git-completion.bash
https://raw.githubusercontent.com/git/git/master/contrib/completion/git-completion.bash
and source that in your bash startup script like .bashrc.
并在您的 bash 启动脚本中提供它，如.bashrc.
But there is a problem with that, because it is referencing the masterbranch, which is the latest version of git-completion.bash. The problem is that sometimes it will break because it is not compatible with the version of git you've installed.
但是有一个问题，因为它引用了master分支，这是git-completion.bash. 问题是有时它会损坏，因为它与您安装的 git 版本不兼容。
In fact, right now that will break because the masterbranch's git-completion.bashhas new features that requires git v2.18, which none of the package managers and installers have updated to yet. You'll get an error unknown option: --list-cmds=list-mainporcelain,others,nohelpers,alias,list-complete,config
实际上，现在这将中断，因为master分支的git-completion.bash新功能需要 git v2.18，而包管理器和安装程序尚未更新到该功能。你会得到一个错误unknown option: --list-cmds=list-mainporcelain,others,nohelpers,alias,list-complete,config
So the safest solution is to reference the version/tag that matches the git you've installed. For example:
因此，最安全的解决方案是引用与您安装的 git 匹配的版本/标签。例如：
https://raw.githubusercontent.com/git/git/v2.17.1/contrib/completion/git-completion.bash
https://raw.githubusercontent.com/git/git/v2.17.1/contrib/completion/git-completion.bash
Note that it has a v2.17.in the URL instead of master. And then, of course, make sure to source that in the bash startup script.
请注意，它v2.17.在 URL 中有一个而不是master。然后，当然，请确保在 bash 启动脚本中找到它的来源。

You just need to source the completion script
您只需要获取完成脚本

on my ubuntu there is a file installed here:
在我的 ubuntu 上，这里安装了一个文件：

you can follow the links into the /usr/lib/git-corefolder. You can find there an instruction, how to set up PS1 or use __git_ps1

May be helpful for someone:--
可能对某人有帮助：--
After downloading the .git-completion.bash from the following link,
从以下链接下载 .git-completion.bash 后，
curl https://raw.githubusercontent.com/git/git/master/contrib/completion/git-completion.bash -o ~/.git-completion.bash
and trying to use __git_ps1 function, I was getting error as--
并尝试使用 __git_ps1 函数，我收到错误 -
-bash: __git_ps1: command not found
Apparently we need to download scripts separately from master to make this command work, as __git_ps1 is defined in git-prompt.sh . So similar to downloading .git-completion.bash , get the git-prompt.sh:
显然我们需要从 master 单独下载脚本才能使这个命令工作，因为 __git_ps1 在 git-prompt.sh 中定义。与下载 .git-completion.bash 类似，获取 git-prompt.sh：
curl -L https://raw.github.com/git/git/master/contrib/completion/git-prompt.sh > ~/.bash_git
and then add the following in your .bash_profile
然后在您的 .bash_profile 中添加以下内容
source ~/.bash_git
if [ -f ~/.git-completion.bash ]; then
. ~/.git-completion.bash
export PS1='\W$(__git_ps1 "[%s]")>'
fi
source ~/.bash.git will execute the downloaded file and
source ~/.bash.git 将执行下载的文件并
export PS1='\W$(__git_ps1 "[%s]")command will append the checkout out branch name after the current working directory(if its a git repository).
export PS1='\W$(__git_ps1 "[%s]")命令将在当前工作目录（如果它是一个 git 存储库）之后附加检出分支名称。
So it will look like:-
所以它看起来像：-
dir_Name[branch_name]where dir_Name is the working directory name and branch_name will be the name of the branch you are currently working on.
dir_Name[branch_name]其中 dir_Name 是工作目录名称， branch_name 将是您当前正在处理的分支的名称。
Please note -- __git_ps1 is case sensitive.
请注意——__git_ps1 区分大小写。

Just do this in your ~/.bashrc:
只需在您的~/.bashrc：
source /usr/share/bash-completion/completions/git
Other answers are telling you to install bash-completion, you don't need to do that, but if you do, then there's no need to source the completion directly. You do one or the other, not both.
其他答案告诉您 install bash-completion，您不需要这样做，但如果您这样做，则无需直接获取完成。你做一个或另一个，而不是两个。
A more generic solution is querying the system location as recommended by the bash-completion project:
一个更通用的解决方案是按照 bash-completion 项目的建议查询系统位置：
source "$(pkg-config --variable=completionsdir bash-completion)"/git

Source /usr/share/git/completion/git-completion.bashin one of the bash startup files.
/usr/share/git/completion/git-completion.bashbash 启动文件之一中的源。
For example:
例如：

You may be able to find the script in other locations like /usr/share/bash-completion/completions/gitbut these scripts did not work for me.
您也许可以在其他位置找到该脚本，/usr/share/bash-completion/completions/git但这些脚本对我不起作用。

Git Bashis the tool to allow auto-completion. Not sure if this is a part of standard distribution so you can find this linkalso useful. By the way, Git Bash allows to use Linux shell commandsto work on windows, which is a great thing for people, who have experience in GNU/Linux environment.
Git Bash是允许自动完成的工具。不确定这是否是标准发行版的一部分，因此您会发现此链接也很有用。顺便说一句，Git Bash 允许使用Linux shell 命令在 Windows 上工作，这对于有 GNU/Linux 环境经验的人来说是一件好事。
