s.txt 内容如下:

i"love"u

用for /f 命令来读取love:

@echo off

for /f "tokens=2 delims="" %%i in (s.txt) do echo %%i

这里的"貌似有问题 执行出错

请各位大大教教小菜 若要将delims指定为" 时，如何实现？

PS.在一个帖子里看到一行命令:

if /i "%~d0"=="c:" (exit) else (cd c:)

这里的%~d0是什么意思？指的是什么？

感谢各位大大不吝赐教

@echo off

set/p var=<s.txt

for /f "tokens=2" %%a in ("%var:"= %") do echo %%a

pause>nul

%~1 - expands %1 removing any surrounding quotes (")
%~f1 - expands %1 to a fully qualified path name
%~d1 - expands %1 to a drive letter only
%~p1 - expands %1 to a path only
%~n1 - expands %1 to a file name only
%~x1 - expands %1 to a file extension only
%~s1 - expanded path contains short names only
%~a1 - expands %1 to file attributes
%~t1 - expands %1 to date/time of file
%~z1 - expands %1 to size of file
%~$PATH:1 - searches the directories listed in the PATH
environment variable and expands %1 to the fully
qualified name of the first one found. If the
environment variable name is not defined or the
file is not found by the search, then this
modifier expands to the empty string

各位前辈早已得出的结论是：双引号"不能做为delims的分隔符！

没想到现在还有人不信这个邪！（当然也可能是前辈们没有找到而已）

@echo off

set str=i"love"u

set str=%str:"=#%

for /f "tokens=2 delims=#" %%i in ("%str%") do echo %%i

嗯。是啊。是不能做为delims的分隔符。
但并不代表不可以用 “ 分隔。。。

感谢各位大大 原来是把"用其他的字符替换…
