修复msysGit便携式$ HOME位置 [英] Fix msysGit Portable $HOME location

问题描述

我已经在我的闪存驱动器上成功安装并配置了msysGit Portable，并用它来拉和推GitHub仓库。然而，我似乎总是不得不嘲笑SSH的支持。

特别是，为了让SSH找到我的密钥文件，我必须遵循这些说明开始第二个实例 ssh-agent ，然后 ssh-add 我的密钥每次运行git -bash.bat。
$ b 使用 ssh -v [e-mail] 的输出进行调试，我可以看到msysGit默认为我的Windows用户目录来查找密钥。它不能那样做;我需要它在自己的便携式驱动器上查找它。

如何强制$ HOME成为程序自己的文件夹？

破坏Vox链接的更新

此页面与我最初发布的现在已断开的链接类似。引用如下。这里还有原始Vox文章的webarchive 。

<但是，如果您尝试此操作并获得：

 ％ssh-add 
无法打开与您的连接认证代理。 
  

那么你的会话没有在ssh-agent下运行。您可以通过运行以下代理重新启动新shell：

  exec ssh-agent bash 
  

您可以用您选择的shell替换bash。一旦你这样做了，你应该能够运行ssh-add来为你的shell加载你的密钥。

解决方案

用于启动git bash的命令是：

  C：\Windows\SysWOW64\cmd.exe / cC：\Prog\Git\1.7.1\bin\\ \\ sh.exe--login -i
  

我在DOS会话中尝试了以下操作：

  C：\> C：\ Windows \SysWOW64\cmd.exe / cC：\\ \\Prog\Git\1.7.1\bin\sh.exe--login -i
 VonC @ XXX / c / 
 $ echo $ HOME 
 / c /用户/ VonC 
  

默认情况下，$ HOME $％HOMEPATH％，但如果强制％HOME％

  set HOME = / another / path 
  

，然后启动相同的bash会话：

  C：\> C： \Windows\SysWOW64\cmd.exe / cC：\Prog\Git\1.7.1\bin\sh.exe--login -i
 VonC @ XXX / c / 
 $ echo $ HOME 
 / another / path 
  

您通过设置HOME的脚本包装bash调用：

• ％〜dp0 ：USB密钥包装的路径


• 或％〜d1 \您的路径：with <$ c
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  $ b $ p>，你应该能够强制HOME给你需要的任何值。

  注意（2011年11月） ， OP dgw 写了他的自己的包装器：
  
  

  git-bash-portable.bat ：

  p>
  
  

    @echo off 
   rem Copyright（C）：2010 Voyagerfan5761 
   rem http://technobabbl.es/ 
   
   set USERPROFILE =％〜dp0 
   set HOMEDRIVE =％〜d0 
   set HOMEPATH =％〜p0 
   set HOME =％〜dp0 
   set HISTFILE =％USERPROFILE％.bash_history 
   rem设置BASHRC =％USERPROFILE％.bashrc 
   
   git-bash.bat 
    

  文章 $ HOME 环境变量以允许完整的可移植性（包括使用SSL密钥和配置）使用GitHub）也添加了有用的信息。

  
  

  但是，如果您将Git安装在便携式硬盘上，你的设置随着安装而移动 - 显然，如果它在其他计算机上可能不存在的文件夹中查找它们，它们不会。

  
  
  

  所以，我们需要做的是告诉便携式Git将自己的文件夹中的特定位置作为主文件夹;这样我们就可以将整个Git文件夹复制到任何我们喜欢的位置，并且设置将随之移动。

  
  

  
  

  I have successfully installed and configured msysGit Portable on my flash drive, and have used it to pull and push GitHub repos. However, I seem to always have to kludge the SSH support.

  Specifically, in order for SSH to find my key files, I have to follow these instructions to start a second instance of ssh-agent and then ssh-add my key every time I run git-bash.bat.

  Using the output of ssh -v [e-mail] to debug I see that msysGit defaults to my Windows user directory to look for keys. It can't do that; I need it to look in its own directory on the portable drive.

  How can I force $HOME to be the program's own folder?

  Update for broken Vox link

  Instructions from this page are similar to the now-broken link I originally posted. Quoted below. Also here's the webarchive of original Vox article.

  However, if you try this and get:

  % ssh-add
  Could not open a connection to your authentication agent. 
  

  then your session is not running under the ssh-agent. You can get around this by restarting a new shell under the agent by running:

  exec ssh-agent bash 
  

  where you can replace bash with the shell of your choice. Once you do this, you should be able to run ssh-add to load your key for that shell.

  解决方案

  The command used to launch git bash is:

  C:\Windows\SysWOW64\cmd.exe /c ""C:\Prog\Git\1.7.1\bin\sh.exe" --login -i"
  

  I just tried the following in a DOS session:

  C:\>C:\Windows\SysWOW64\cmd.exe /c ""C:\Prog\Git\1.7.1\bin\sh.exe" --login -i"
  VonC@XXX /c/
  $ echo $HOME
  /c/Users/VonC
  

  By default, $HOME$%HOMEPATH%, but if I force %HOME%:

  set HOME=/another/path
  

  and then launch the same bash session:

  C:\>C:\Windows\SysWOW64\cmd.exe /c ""C:\Prog\Git\1.7.1\bin\sh.exe" --login -i"
  VonC@XXX /c/
  $ echo $HOME
  /another/path
  

  So if you wrap the bash call by a script setting the HOME to:

  • %~dp0 : the path of the wrapper on your USB key
  • or %~d1\your\path: with %~d1 being the drive letter (of your usb key if your wrapper is on it)

  , you should be able to force HOME to whatever value you need.

  Note (November 2011): since then, the OP dgw has written his own wrapper:

  git-bash-portable.bat:

  @echo off
  rem Copyright (C): 2010 Voyagerfan5761
  rem http://technobabbl.es/
  
  set USERPROFILE=%~dp0
  set HOMEDRIVE=%~d0
  set HOMEPATH=%~p0
  set HOME=%~dp0
  set HISTFILE=%USERPROFILE%.bash_history
  rem set BASHRC=%USERPROFILE%.bashrc
  
  git-bash.bat
  

  The article "Portable Git for Windows: setting the $HOME environment variable to allow complete portability (including SSL keys and configuration for use with GitHub)" also add useful information.

  However, if you install Git on a portable drive, you'll want your settings to travel with the installation—which obviously they won't if it is looking for them in a folder which may not exist on other computers.

  So, what we need to do is tell Portable Git to treat a specific location within its own folder as the home folder; that way we can copy the whole Git folder anywhere we like and the settings will travel with it.
