China DOS Union

Today on duty, really bored. CS was beaten by others, QQ has no one to chat with. Want to write a bat but can't figure it out. Fainted on the front line.
Hope brothers can give pointers.

setlocal EnableDelayedExpansion

set m=0

for /f "tokens=*" %%m in ('findstr /v /C:"730 730" cover.ps') do ( 



    if !m!












If using set and then echo, then the % in the text will be replaced.  

If using call, and not enabling variable delay, when passing %%m of for to call, the same thing will be lost.

So I still enabled variable delay, and the result is that the! are all gone. Hope experts can give advice.

Since variable delay is used, why still use %m% to reference? It should be changed to !m! instead.

I tested the following code, it has already added 1. What exactly do you want it to become?

Specifically, whether there is a problem with the code, because the function you want to implement is unclear, I didn't look closely, but at least it can add 1, otherwise you can give it a try.

@echo off

setlocal EnableDelayedExpansion

set m=0

for /f "tokens=*" %%m in ('findstr /v /C:"730 730" cover.ps') do ( 



    if %m%

Hope the experts can give an idea! Thanks

setlocal EnableDelayedExpansion
set m=0
for /f "tokens=* delims=" %%m in ('findstr /v /C:"730 730" cover.ps') do (
if "!m!"=="686" (pause) else echo %%m >>cover3.txt
set /a m=!m!+1
)
pause
exit
I don't know what effect the original poster wants. There is nothing wrong with this batch script

This is this meaning. If once there is an exclamation mark in cover.ps, because the variable delay is enabled, this exclamation mark cannot be echoed into the new file.

@echo off
set m=0
for /f "tokens=*" %%m in ('findstr /v /C:"730 730" 2.txt') do (
setlocal EnableDelayedExpansion
set /a m=!m!+1
if "!m!"=="686" (pause) else setlocal DISABLEDELAYEDEXPANSION&&echo %%m>>test.txt
)
echo %m%

The method is a bit crude, but this issue needs to be considered. The original poster can try this first

Exceeded the maximum setlocal recursion depth.
Exceeded the maximum setlocal recursion depth.

This is the run record

And the exclamation mark is still gone

It seems that this problem occurs with repeated calls, but it's okay if the number of lines is small. I just tested it and didn't expect this problem. I'm thinking about it.

What system are you using? I tested with Windows 2000

Re kcdsw:

First of all, set/a has an independent variable recognition mechanism, and there is no need to use the form of!m! for delayed variable expansion. You can directly use set /a m+=1. However, using set /a m=%m%+1 in building 3 will instead have the problem of not being able to continuously increase because it always uses the initialized variable.

Secondly, regarding the problem of! being escaped in the text, the solution is still to turn off variable delay and use call, but when passing %%m, it is no longer using command line parameters, but using environment variables. As follows:

@echo off

set m=0

for /f "tokens=*" %%m in ('findstr /v /C:"730 730" cover.ps') do (

    set line=%%m

    call :Output

    set /a m+=1

)

pause

exit



:Output

if "%m%" == "686" (pause) else (echo %line% >>cover3.txt)

goto :eof

Oh, I see......

Tears shed tears and.... continue posting

I uploaded it

The purpose is to have the line containing 730 730, and recalculate its width through the pixel data of the next line
ps: 730 730 are the length and width values, but the original photo is not a square, so the length and width ratio is wrong. I want to use this to change it to the correct one, but I accidentally lost the exclamation mark

My environment is xp sp2 (oem genuine version)
