如何在安装后更改我的Cygwin主文件夹？ [英] How can I change my Cygwin home folder after installation?

问题描述

我刚刚安装Cygwin，它看起来像主目录在bash提示符是在我的Z：驱动器。

解决方案

从Cygwin 1.7.34开始< a>，推荐的方法是向 /etc/nsswitch.conf 中添加自定义 db_home 设置。这样做的一个共同的愿望是使您的Cygwin主目录等于您的Windows用户配置文件目录。此设置将执行以下操作：

  db_home：windows 
  

或者，等价于：

  db_home：/％H 
  

您需要使用后一种形式，如果你想在这个方案的一些变化，如隔离您的Cygwin主文件您的Windows用户个人资料目录的子目录：

  db_home：/％H / cygwin 
  Windows 选项加上几个其他的替代方案有 c>其他％令牌可以代替％H 或除此之外。请参见  nsswitch.conf  code>语法说明，位于 Cygwin用户指南。
 
 
 
如果您在1.7.34之前安装了Cygwin或者已经运行  mkpasswd 实用程序，以便您拥有 / etc / passwd 文件，可以通过编辑用户在该文件中的条目来更改Cygwin主目录。您的主目录是您的用户在 / etc / passwd 中的第二个到最后一个元素。
 
 
 
无论以何种方式，这将导致在shell启动期间设置 HOME 环境变量。

虽然可以通过控制面板设置％HOME％，但正式阻止。它不仅不经意地覆盖了上面的机制，而且并不总是可行，比如通过 cron 运行shell脚本。
 
 
 
 
I just installed Cygwin, and it looks like the home directory in the bash prompt is on my Z: drive. That's not where I want it.

How can I change this?
解决方案
Starting with Cygwin 1.7.34, the recommended way to do this is to add a custom db_home setting to /etc/nsswitch.conf. A common wish when doing this is to make your Cygwin home directory equal to your Windows user profile directory. This setting will do that:
db_home: windows
Or, equivalently:
db_home: /%H
You need to use the latter form if you want some variation on this scheme, such as to segregate your Cygwin home files into a subdirectory of your Windows user profile directory:
db_home: /%H/cygwin
There are several other alternative schemes for the windows option plus several other % tokens you can use instead of %H or in addition to it. See the nsswitch.conf syntax description in the Cygwin User Guide for details.

If you installed Cygwin prior to 1.7.34 or have run its mkpasswd utility so that you have an /etc/passwd file, you can change your Cygwin home directory by editing your user's entry in that file. Your home directory is the second-to-last element on your user's line in /etc/passwd.¹

Whichever way you do it, this causes the HOME environment variable to be set during shell startup.²

See this FAQ item for more on the topic.



Footnotes:

Consider moving /etc/passwd and /etc/group out of the way in order to use the new SAM/AD-based mechanism instead.
While it is possible to simply set %HOME% via the Control Panel, it is officially discouraged. Not only does it unceremoniously override the above mechanisms, it doesn't always work, such as when running shell scripts via cron.
