如何在Windows 7中永久自定义命令提示符？

我想改变提示 $p$g$_$f 永久，但每次重新打开命令窗口时它都会重置。

我怎样才能让它永远永远保持不变？

创建一个名为PROMPT的新环境变量。将变量值设置为所需的提示。

在命令提示符下键入：

 SETX  提示$ p $ g $ _ $ f 

然后重新打开命令提示符。

对于任何不知道如何获得DOS / CMD命令帮助的人，请键入：

setx /?

要得到：

SetX has three ways of working:

Syntax 1:
    SETX [/S system [/U [domain\]user [/P [password]]]] var value [/M]

Syntax 2:
    SETX [/S system [/U [domain\]user [/P [password]]]] var /K regpath [/M]

Syntax 3:
    SETX [/S system [/U [domain\]user [/P [password]]]]
         /F file {var {/A x,y | /R x,y string}[/M] | /X} [/D delimiters]

Description:
    Creates or modifies environment variables in the user or system
    environment. Can set variables based on arguments, regkeys or
    file input.

Parameter List:
    /S     system          Specifies the remote system to connect to.

    /U     [domain\]user   Specifies the user context under which
                           the command should execute.

    /P     [password]      Specifies the password for the given
                           user context. Prompts for input if omitted.

    var                    Specifies the environment variable to set.

    value                  Specifies a value to be assigned to the
                           environment variable.

    /K     regpath         Specifies that the variable is set based
                           on information from a registry key.
                           Path should be specified in the format of
                           hive\key\...\value. For example,
                           HKEY_LOCAL_MACHINE\System\CurrentControlSet\
                           Control\TimeZoneInformation\StandardName.

    /F     file            Specifies the filename of the text file
                           to use.

    /A     x,y             Specifies absolute file coordinates
                           (line X, item Y) as parameters to search
                           within the file.

    /R     x,y string      Specifies relative file coordinates with
                           respect to "string" as the search parameters.

    /M                     Specifies that the variable should be set in
                           the system wide (HKEY_LOCAL_MACHINE)
                           environment. The default is to set the
                           variable under the HKEY_CURRENT_USER
                           environment.

    /X                     Displays file contents with x,y coordinates.

    /D     delimiters      Specifies additional delimiters such as ","
                           or "\". The built-in delimiters are space,
                           tab, carriage return, and linefeed. Any
                           ASCII character can be used as an additional
                           delimiter. The maximum number of delimiters,
                           including the built-in delimiters, is 15.

    /?                     Displays this help message.

NOTE: 1) SETX writes variables to the master environment in the registry.

      2) On a local system, variables created or modified by this tool
         will be available in future command windows but not in the
         current CMD.exe command window.

      3) On a remote system, variables created or modified by this tool
         will be available at the next logon session.

      4) The valid Registry Key data types are REG_DWORD, REG_EXPAND_SZ,
         REG_SZ, REG_MULTI_SZ.

      5) Supported hives:  HKEY_LOCAL_MACHINE (HKLM),
         HKEY_CURRENT_USER (HKCU).

      6) Delimiters are case sensitive.

      7) REG_DWORD values are extracted from the registry in decimal
         format.

Examples:
    SETX MACHINE COMPAQ
    SETX MACHINE "COMPAQ COMPUTER" /M
    SETX MYPATH "%PATH%"
    SETX MYPATH ~PATH~
    SETX /S system /U user /P password  MACHINE COMPAQ
    SETX /S system /U user /P password MYPATH ^%PATH^%
    SETX TZONE /K HKEY_LOCAL_MACHINE\System\CurrentControlSet\
         Control\TimeZoneInformation\StandardName
    SETX BUILD /K "HKEY_LOCAL_MACHINE\Software\Microsoft\Windows
         NT\CurrentVersion\CurrentBuildNumber" /M
    SETX /S system /U user /P password TZONE /K HKEY_LOCAL_MACHINE\
         System\CurrentControlSet\Control\TimeZoneInformation\
         StandardName
    SETX /S system /U user /P password  BUILD /K
         "HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\
         CurrentVersion\CurrentBuildNumber" /M
    SETX /F ipconfig.out /X
    SETX IPADDR /F ipconfig.out /A 5,11
    SETX OCTET1 /F ipconfig.out /A 5,3 /D "#$*."
    SETX IPGATEWAY /F ipconfig.out /R 0,7 Gateway
    SETX /S system /U user /P password  /F c:\ipconfig.out /X

要更改DOS提示符（或“命令提示符”）的外观，请右键单击“计算机”（通常在Windows桌面或Windows“开始”菜单中），然后按照下列步骤操作：

1. 单击“高级系统设置”标签
2. 单击“环境变量...”按钮
3. 单击“新建...”按钮（“用户变量”仅影响您，“系统变量”影响所有用户）
4. 创建一个名为“PROMPT”的变量并插入所需的提示文本（正如我在下面的最后一张图片中所包含的那样）
5. 单击“确定”按钮以关闭“环境变量”窗口
6. 单击“确定”按钮以关闭“系统属性”窗口

此更改也将在重新启动后继续存在。

编辑菜单命令或链接，启动命令提示符，更改其目标，例如。

%SystemRoot%\system32\cmd.exe /K "prompt $p$g$_$f"

如果在光标前需要额外的空间：

%SystemRoot%\system32\cmd.exe /K "prompt $p$g$_$f "

Windows附带Windows PowerShell，允许在其他以前的Linux专用功能中进行流水线操作。

您可以通过单击“开始”按钮并输入PowerShell来启动它，它为您提供了三个选项。单击PowerShell。右键单击窗口标题栏，然后选择“属性”。在打开的窗口中，您可以配置视图和行为设置。

否则，不要先打开PowerShell，然后选择并单击PowerShell模块。

有关您可以执行的操作，请参阅Microsoft文档：

• http://msdn.microsoft.com/en-us/library/aa717060(v=vs.85).aspx

PS：如果您开发控制台应用程序，我不推荐使用经典shell。

确定方法：

setx prompt ""

对于所有用户：

setx prompt "" /M

提示可自定义的示例，带样式：

setx PROMPT "$_$e[0;1;44mN$e[1;30;47mI$e[0;1;44mC$E[35;40m $d$s$t$h$h$h$h$h$h$_$E[1;33;40m$p$_$E[0;0m~$g$s"
