轉義「）」在Windows批處理「的命令

Question

我需要迭代文件中的行。以下命令不起作用：

set filename=c:\program files (x86)\somewhere 
... 
for /f "delims==" %%i in (%filename%) do echo %%i 

因爲「）」在文件名中。錯誤：

\somewhere) was unexpected at this time. 

由「^」轉義不起作用，因爲我需要使用變量而不是內聯文件名。如何解決這個問題？

Answer 1

將在雙引號中的文件名，而且還添加了usebackq選項：

set filename=c:\program files (x86)\somewhere 
for /f "usebackq delims==" %%i in ("%filename%") do echo %%i 

從FOR /?輸出：

usebackq  - specifies that the new semantics are in force, 
        where a back quoted string is executed as a 
        command and a single quoted string is a 
        literal string command and allows the use of 
        double quotes to quote file names in 
        file-set. 

Answer 2

set filename=c:\program files (x86)\somewhere 
... 
for /f "USEBACKQ delims==" %%i in ("%filename%") do echo %%i 

有usebackq允許您使用的路徑雙引號與空間
