英文:
joining lines while adding white-spaces to select strings in CMD is not working
问题
翻译结果如下：
我的测试字符串是：
这是一个句子。
google.com
这是另一个句子。
microsoft.com
这个句子没有句号
我的代码是：
@echo off
setlocal EnableDelayedExpansion
set row=
@((For /F "EOL=|Delims=" %%# In ('"%AppDir%find.exe" "."^<"%UserProfile%\i.txt"')Do @Set /P "=%%# "<NUL)&Echo()>"%UserProfile%\o.txt"
echo %row% >%userprofile%\o.txt
echo %row%
C:\Users\qwerp>joint3
ECHO is off.
我期望得到的是：
google.com microsoft.com
但实际上我得到的是：
ECHO is off.
我做错了什么？

给定您的示例文件内容更改和所述意图，这可能足以满足您的需求，只需将 find.exe 更改为 findstr.exe，（使用适当的选项）：
@((For /F "EOL=|Delims=" %%# In ('"%__AppDir__%findstr.exe" "\." "%UserProfile%\i.txt"^|"%__AppDir__%findstr.exe" "[^\.]$"')Do @Set /P "=%%# "<NUL)&Echo()>"%UserProfile%\o.txt"
英文:
Given your example file content change and the stated intention, this may be sufficient for your needs, simply changing find.exe to findstr.exe, (with appropriate options):
<!-- language: lang-bat -->
@((For /F "EOL=|Delims=" %%# In ('^""%__AppDir__%findstr.exe" "\." "%UserProfile%\i.txt"^|"%__AppDir__%findstr.exe" "[^\.]$"^"')Do @Set /P "=%%# "<NUL)&Echo()>"%UserProfile%\o.txt"
