cmd：将 wmic 输出保存到变量

我正在尝试将文件的时间戳放入批处理文件中的变量中。

我的批处理文件 imagetime.bat 包含以下内容：

set targetfile=%~1
set targetfile=%targetfile:\=\\%
echo %targetfile%
for /f "usebackq delims=" %%i in ( `wmic datafile where name^="%targetfile%" get creationdate` ) do ( echo %%i )
echo %timestamp%

我得到这个输出：

C:\>imagetime.bat V:\setup.exe

C:\>set targetfile=V:\setup.exe

C:\>set targetfile=V:\\setup.exe

C:\>echo V:\\setup.exe
V:\\setup.exe

C:\>for /F "usebackq delims=" %i in (`wmic datafile where name="V:\\setup.exe" g
et creationdate`) do (echo %i  )

  ) (echo CreationDate
 reationDate

  ) (echo 20110412103858.000000+***
 0110412103858.000000+***

  ) (echo
ECHO is on.

C:\>echo ""
""

C:\>

当然，最后我希望看到“20110412103858.000000+***”，这样我就可以用cmd的字符串操作将其格式化为“04/12/2011,10:38:58”。

我究竟做错了什么？

Update

我尝试了Hackoo的解决方案。它适用于 calc.exe，但不适用于 V:\setup.exe。删除 @echo 关闭并暂停后，我得到此输出（我将引用 calc.exe 的行更改为：set "targetfile=V:\setup.exe"):

C:\>hackoo_calc.bat

C:\>set "targetfile=C:\Windows\system32\calc.exe"

C:\>set targetfile=C:\\Windows\\system32\\calc.exe

C:\>for /F "usebackq delims=" %i in (`wmic datafile where name="C:\\Windows\\sys
tem32\\calc.exe" get creationdate`) do (for %b in (%i) do (set "timestamp=%b" )
)

) do (set "timestamp=%b" ) )

C:\>(set "timestamp=CreationDate" )

) do (set "timestamp=%b" ) ) 1.688252+120

C:\>(set "timestamp=20090714015711.688252+120" )

) do (set "timestamp=%b" ) )

C:\>echo TimeStamp : "20090714015711.688252+120"
TimeStamp : "20090714015711.688252+120"

C:\>hackoo_setup.bat

C:\>set "targetfile=V:\setup.exe"

C:\>set targetfile=V:\\setup.exe

C:\>for /F "usebackq delims=" %i in (`wmic datafile where name="V:\\setup.exe" g
et creationdate`) do (for %b in (%i) do (set "timestamp=%b" ) )

) do (set "timestamp=%b" ) )

C:\>(set "timestamp=CreationDate" )

) do (set "timestamp=%b" ) ) 8.000000+***

) do (set "timestamp=%b" ) )

C:\>echo TimeStamp : "CreationDate"
TimeStamp : "CreationDate"

C:\>

这会做你想要的吗？

@Echo Off
Set "TF=%~f1"
Set "TS="
For /F "Skip=1" %%A In ('WMIC DataFile Where^
 "Name='%TF:\=\\%'" Get CreationDate') Do For %%B In (%%~nA) Do Set "TS=%%B"
If Not Defined TS Exit /B
Set "TS=%TS:~4,2%/%TS:~6,2%/%TS:~,4%,%TS:~-6,2%:%TS:~-4,2%:%TS:~-2%"
Echo %TS%
Pause

[Edit]

这里再次使用正常的命令行风格，没有插入符号：

With UseBackQ:

@Echo Off
Set "TF=%~f1"
Set "TS="
For /F "UseBackQ Skip=1" %%A In (`
    "WMIC DataFile Where Name="%TF:\=\\%" Get CreationDate"
`) Do For %%B In (%%~nA) Do Set "TS=%%B"
If Not Defined TS Exit /B
Set "TS=%TS:~4,2%/%TS:~6,2%/%TS:~,4%,%TS:~-6,2%:%TS:~-4,2%:%TS:~-2%"
Echo %TS%
Pause

Without UseBackQ: （首选）

@Echo Off
Set "TF=%~f1"
Set "TS="
For /F "Skip=1" %%A In ('
    "WMIC DataFile Where Name="%TF:\=\\%" Get CreationDate"
') Do For %%B In (%%~nA) Do Set "TS=%%B"
If Not Defined TS Exit /B
Set "TS=%TS:~4,2%/%TS:~6,2%/%TS:~,4%,%TS:~-6,2%:%TS:~-4,2%:%TS:~-2%"
Echo %TS%
Pause
