Prevent removing of blank lines....

[pditty8811]

I have some code here, but it removes all the blank lines in 2.txt. How to prevent this?

Thank you.

Code: Select all

@echo off

copy 2.txt 2.txt-backup

setlocal enableDelayedExpansion

>2.txt (
    for /f "delims=" %%A in (2.txt-backup) do (
        ( echo !ln!| findstr "^Type=206$" >NUL && (
            set ln=ln
        ) ) || (
            set "ln=%%A"
            if "!ln:~0,6!"=="Class=" (
                findstr /c:"ClassName=!ln:~6!" Log_*.txt >null && (
                    echo Class=ShipDummy
                    set "ln=Type=206"
                )
            )
            echo !ln!
        )
    )
)

One short suggestion:

Code: Select all

@echo off

copy 2.txt 2.txt-backup

setlocal enableDelayedExpansion

>2.txt (
   for /f "tokens=1*delims=:" %%A in ('type 2.txt-backup ^| findstr /n $') do (
      ( echo !ln!| findstr "^Type=206$" >NUL && (
            set ln=ln
        ) ) || (
            set "ln=%%B"
            if "!ln:~0,6!"=="Class=" (
                findstr /c:"ClassName=!ln:~6!" Log_*.txt >null && (
                    echo Class=ShipDummy
                    set "ln=Type=206"
                )
            )
            echo.!ln!
        )
    )
)

Thank you very much.

Now, what if I wanted to use as the variable, instead of what came after ClassName= in 1.txt, what came in between (for example):

EntryText=Ship sunk!|Grid AO 77| Grab variable HERE,

So grab after the text line ending with the second | and before the comma.

The text line will be the same EXCEPT after Grid there could be a word or a different two pair of letters and numbers.


So this is what I am trying to use as a variable, what is in between:

EntryText=Ship sunk!|Grid (Any combination of letters or words followed by a| This is what I'd like to replace within the code after ClassName= and a comma.

So grab in between the second | and the comma
