Is this okay?? Limited to output

type test.txt>output.txt

?
Which post is the post above targeting?

I think when the number of quotation marks is odd, all the content after echo will be output;
Therefore, redirection is not possible;
I think the solution is to escape each quotation mark;

For even numbers, I think there will be no mistakes

Hehe, the code I'm using is not your version, the statement is wrong, I take back this statement.

Unknowingly, bjsh has solved all the output problems of special characters, and the remaining tasks are efficiency improvement and code simplification/standardization.

Is this okay?? Only for output

type test.txt>output.txt

　　The type method is only limited to the output of the entire text, but what I want to discuss is the original output of all special characters in the content of the specified line. My title is a bit misleading, so I'll change it.

@echo off

if exist tmp.txt del tmp.txt

set var=

for /f "delims=" %%a in ('findstr /n .* test.txt') do (

set "var=%%a"

call set "var=%%var:"=%%"

call :change

)

goto :eof

:change

set "var=%var:^=^^%"

set "var=%var:>=^>%"

set "var=%var:<=^<%"

set "var=%var:&=^&%"

set "var=%var:|=^|%"

set "var=%var:*:=%"

if not defined var echo.>>tmp.txt & goto :eof

call set "var=%%var:="%%"

call echo.%%var%%>>tmp.txt

Redirect to the code in the text

@echo off

if exist tmp.txt del tmp.txt

set var=

for /f "delims=" %%a in ('findstr /n .* test.txt') do (

set "var=%%a"

call set "var=%%var:"=%%"

call :change

)

goto :eof

:change

set "var=%var:^=^^%"

set "var=%var:>=^>%"

set "var=%var:<=^<%"

set "var=%var:&=^&%"

set "var=%var:|=^|%"

set "var=%var:*:=%"

if not defined var echo.>>tmp.txt & goto :eof

call set "var=%%var:="%%"

call echo.%%var%%>>tmp.txt

Notes:
In "call set "var=%%var:"=%%"", the " " in "%%" is not a space but a special character from ctrl+BackSpace;

I remember there was a very good solution in the post with the signature of Wuna iHe already!

@echo off

for /f "delims=" %%a in ('findstr /n .* test.txt') do (

        set "var=%%a"

        setlocal enabledelayedexpansion

        set var=!var:*:=!

        echo.!var!

        endlocal

)

Latest code:
Concise and efficient

@echo off

for /f "delims=" %%a in ('findstr /n .* test.txt') do (

        set "var=%%a"

        setlocal enabledelayedexpansion

        set var=!var:*:=!

        echo.!var!

        endlocal

)

Interested people help test

This might be the most concise and efficient code. There's a lot to be done with variable delays.

A brief analysis of the subtle relationship among environment variables, special characters for variable delay, and the intermediate method

This is the afterthought of writing the above code.

@echo off

for /f "eol= delims=" %%i in (a.txt) do (

set type=%%i

for /l %%j in (0,1,100) do (

setlocal EnableDelayedExpansion

if "!type:~%%j,1!"==" " (set/p= <nul)

if "!type:~%%j,1!"=="=" (set/p= <nul&set/p==<nul) else (

call set/p="%%type:~%%j,1%%"<nul)

endlocal)

echo.

)

pause>nul

I don't know how the effect will be..

Hehe `Not bad` `Admire` ``

Benefited a lot!
But there is still one problem: How to modify the text containing special symbols with P? For example:
Change test.txt
ip 125.219.59.216

sv_contact "568ggstart@163.Com"
// Contact email of the server builder

sv_send_resources 1
// Automatically send resource files included in the *.res file associated with the map to the client

sv_maxrate 25000
// Server maximum transmission rate <0-25000>

to:
ip 59.32.211.105

sv_contact "568ggstart@163.Com"
// Contact email of the server builder

sv_send_resources 1
// Automatically send resource files included in the *.res file associated with the map to the client

sv_maxrate 25000
// Server maximum transmission rate <0-25000>

It's too profound. It's hard to say not to top it after just reading. But I'm afraid that topping it would make me look like an amateur joining in. Still, I'll top it.
