为什么Git config list（total）与system + global + local不一样 [英] Why Git config list (total) is not the same as system + global + local

问题描述

在Windows上的Git 2.6.3上，为什么这个命令会导致：

  git config --list 
  

与其他人不一样：

  git config --list --system 
 git config --list --global 
 git config --list --local 
  

第一个列出的选项比其他选项总和多一些。我已重定向到文件和kdiff比较，并有差异。

根据要求，这是 git config --list ，而不是在system / global / local分组：

  core.symlinks = false 
 core .autocrlf = true 
 color.diff = auto 
 color.status = auto 
 color.branch = auto 
 color.interactive = true 
 pack.packsizelimit = 2g 
 help.format = html 
 http.sslcainfo = C：/ Program Files（x86）/Git/mingw32/ssl/certs/ca-bundle.crt 
 sendemail.smtpserver = / bin / msmtp .exe 
 diff.astextplain.textconv = astextplain 
 rebase.autosquash = true 
  

上面列出的那个配置（不是在system / global / local）值保存在哪里？ TL; DR ： C：\Users\All Users\Git\config 。

请参阅

在 C：\程序数据\Git ，我看到额外的值：

  C：\程序数据\Git>更多配置
 [core] 
 symlinks = false 
 autocrlf = true 
 [color] 
 diff = auto 
 status = auto 
 branch = auto 
 interactive = true 
 [pack] 
 packSizeLimit = 2g 
 [help] 
 format = html 
 [http] 
 sslCAInfo = C：/ Program Files / Git / mingw64 / ssl / certs / ca-bundle.crt 
 [sendemail] 
 smtpserver = / bin / msmtp.exe 
 
 [diffastextplain] 
 textconv = astextplain 
 [rebase] 
 autosquash = true 
  

正如 ProgramData 文件夹在Windows？，该文件夹是 All Users 中的一个：

  C：\ Users \所有用户\Git> dir 
驱动器C中的卷没有标签。 
 
 C：\ Users \ All Users\Git 
 
 23/10/2015 16:36< DIR> 。 
 23/10/2015 16:36< DIR> .. 
 23/10/2015 16:36 350 config 
  

On Git 2.6.3 on Windows, why this command result:

git config --list

Is not the same as this others:

git config --list --system
git config --list --global
git config --list --local

The first one has a few more options listed than the sum of the others. I have redirected to files and kdiff compare and there are differences.

As requested this is the values there are in git config --list and not in the system/global/local grouped:

core.symlinks=false
core.autocrlf=true
color.diff=auto
color.status=auto
color.branch=auto
color.interactive=true
pack.packsizelimit=2g
help.format=html
http.sslcainfo=C:/Program Files (x86)/Git/mingw32/ssl/certs/ca-bundle.crt
sendemail.smtpserver=/bin/msmtp.exe
diff.astextplain.textconv=astextplain
rebase.autosquash=true

Where are that config quoted above (not in system/global/local) values saved?

解决方案

TL;DR: C:\Users\All Users\Git\config.
See git-for-windows PR 470

On Windows, as there is no central /etc/ directory, there is yet another config file (located at %PROGRAMDATA%\Git\config), intended to contain settings for all Git-related software running on the machine.
Consequently, this config file takes an even lower precedence than the $(prefix)/etc/gitconfig file.

You can check that (with git 2.8+, March 2016), by typing

git config --list --show-origin

See "Where do the settings in my Git configuration come from?"

---

As mentioned in git config FILES, git is looking for values (or default values if not found) of configs in 3 places (outside the git repo itself)

$(prefix)/etc/gitconfig

System-wide configuration file.

$XDG_CONFIG_HOME/git/config

Second user-specific configuration file.
If $XDG_CONFIG_HOME is not set or empty, $HOME/.config/git/config will be used. Any single-valued variable set in this file will be overwritten by whatever is in ~/.gitconfig. It is a good idea not to create this file if you sometimes use older versions of Git, as support for this file was added fairly recently.

~/.gitconfig

User-specific configuration file. Also called "global" configuration file.

But a quick process monitor mentions a fourth place (again, outside a git repo itself)

In C:\ProgramData\Git, I see the extra values:

C:\ProgramData\Git>more config
[core]
        symlinks = false
        autocrlf = true
[color]
        diff = auto
        status = auto
        branch = auto
        interactive = true
[pack]
        packSizeLimit = 2g
[help]
        format = html
[http]
        sslCAInfo = C:/Program Files/Git/mingw64/ssl/certs/ca-bundle.crt
[sendemail]
        smtpserver = /bin/msmtp.exe

[diff "astextplain"]
        textconv = astextplain
[rebase]
        autosquash = true

As mentioned in "What is the significance of the ProgramData folder in Windows?", that folder is the one from All Users:

C:\Users\All Users\Git>dir
 Volume in drive C has no label.

 Directory of C:\Users\All Users\Git

23/10/2015  16:36    <DIR>          .
23/10/2015  16:36    <DIR>          ..
23/10/2015  16:36               350 config
