我正在尝试从命令提示符检查并更新注册表中的网络区域映射。我需要检查名为的值*
。例如,在HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet 设置\ZoneMap\Domains\cmich.local,注册表编辑器显示以下内容:
* REG_DWORD 0x00000001 (1)
为了在命令脚本 (*.cmd) 中检查此值,我一直尝试使用 REG QUERY 命令。当我尝试通过传递*
要匹配的值来执行此操作时,REG QUERY 命令会将星号视为通配符,只要该键存在,它就会返回匹配项。
reg query "HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings\ZoneMap\Domains\example.com" /v "*" /reg:64
我尝试了多种转义字符组合(甚至那些我非常确定不会起作用的组合),包括以下所有带引号和不带引号的组合:,,,,,,。*
这些都不起作用。\*
^*
`*
`*`
!*
我还需要添加和删除名为的值*
,大概使用 REG ADD 和 REG DELETE。
*
如何在命令提示符下添加、删除和测试具有名称的注册表值是否存在?
答案1
检查注册表值的一个棘手部分是命名*
(实际上是一个含义通配符全部):
?
使用通配符仅查询单字符命名值,即最多一个字符, 和- 将结果缩小到
*
使用命名的值findstr
公用事业;- 事实上,
reg query "%_TestKey%" /v ? | findstr /I /C:" * REG_"
就足够了。
- 事实上,
以下批处理文件代码片段显示添加、删除或更改名为 的值没有问题*
。
代码如下评论使用<NUL set /P =::: …
技巧,即echo ::: …
没有结尾CRLF,以最少的空行在输出中显示注释。
@ECHO ON
@SETLOCAL EnableExtensions DisableDelayedExpansion
@<NUL set /P =::: define a registry key
set "_TestKey=HKEY_CURRENT_USER\Software\Test Key"
@<NUL set /P =::: check all one-character named values
reg query "%_TestKey%" /v ?
@<NUL set /P =::: narrow above result to the value named * using findstr utility
reg query "%_TestKey%" /v ? | findstr /I /C:"%_TestKey%" /C:" * REG_"
@<NUL set /P =::: delete the value named *
reg delete "%_TestKey%" /v * /f
@<NUL set /P =::: add the value named *
reg add "%_TestKey%" /v * /t REG_DWORD /d 4 /f
@<NUL set /P =::: check the value named *
reg query "%_TestKey%" /v ? | findstr /I /C:"%_TestKey%" /C:" * REG_"
@<NUL set /P =::: change the value named *
reg add "%_TestKey%" /v * /t REG_DWORD /d 1 /f
@<NUL set /P =::: check the value named *
reg query "%_TestKey%" /v ? | findstr /I /C:"%_TestKey%" /C:" * REG_"
