I have read this post http://www.cn-dos.net/forum/viewthread.php?tid=25172

The method in it can handle ordinary documents, but there will be problems when used to handle batch files. I want to ask if it can be done through findstr (intercepting from the first non - space character of each line to the last character).

@echo off

for /f "tokens=*" %%a in (test.txt) do echo %%a

pause

```@echo off
for /f "tokens=*" %%a in (test.txt) do echo %%a
pause
```

VBS function - LTRIM is easier...

echo           ------------------------------

echo           ^|      无效程序         ^|

echo           ------------------------------

echo           ------------------------------

echo           |      无效程序         |

echo           ------------------------------

Is this???

This is in that post...
No...

When encountering such a statement, the output changes

echo           ------------------------------

echo           ^|      Invalid Program         ^|

echo           ------------------------------

After output

echo           ------------------------------

echo           |      Invalid Program         |

echo           ------------------------------

As a result, when running, the vertical bar "|" will be treated as a pipe, and the result will be wrong...

Please make the problem clearer, I don't quite understand.

I tested and there are no problems.

It is the text in the original file:
echo ------------------------------
echo ^| ^|
echo ^| 无效程序 ^|
echo ------------------------------
After the processing of removing spaces, it becomes like this:
echo ------------------------------
echo ^| ^|
echo | 无效程序 |
echo ------------------------------
Only when there are Chinese characters will this happen. In the second line of echo, it is still output as originally, but in the third line, the original ^| is output as |, and in this way, executing the program after removing spaces will cause errors...

# type test.txt
echo ------------------------------
echo ^| ^|
echo ^| Invalid Program ^|
echo ------------------------------

# type Deal_test.bat
@echo off
for /f "tokens=*" %%a in (test.txt) do echo %%a
pause

# Deal_test.bat
echo ------------------------------
echo ^| ^|
echo ^| Invalid Program ^|
echo ------------------------------
Press any key to continue. . .

@echo off

if %1.==. (set /p file=input:) else (set file=%1)

for /f "delims=" %%i in ("%file%") do (set file="%%~i"&set file0=%%~dpi&set file1=%%~nxi)

for /f "tokens=*" %%a in ('findstr /v "REM ::" %file%') do echo %%a>>"%file0%Deal_%file1%"

Hehe... I tested it and it really works... I used the same command... Why was it like that that day...

Maybe it's a problem with the machine...
By the way, post a small program of the streamlined batch file I made. It has only 3 lines. Don't laugh at me oh...

(Function: Delete comments, delete blank lines and spaces at the beginning of each line)

@echo off
