Removing all text after a certain line/character

[Carbon Dudeoxide]

if the file you wanted to edit was a batch file like this:

Code: [Select]

@echo off
echo hello
echo how are you
echo.
pauseand say you wanted to add a "echo i'm good", do this:

Code: [Select]

@echo off
del "C:\path\file.bat"
echo @echo off >>"C:\path\file.bat"
echo echo hello >>"C:\path\file.bat"
echo echo how are you >>"C:\path\file.bat"
echo echo. >>"C:\path\file.bat"
echo echo I'm good >>"C:\path\file.bat"
echo pause >>"C:\path\file.bat"

This would delete the old one and create a new file with the added sentence.
The finished product would be:

Code: [Select]

@echo off
echo hello
echo how are you
echo.
echo I'm good
pause

wow fantastic! but what has this got to do with what OP wants?

well....he wanted to replace a line of text....
This is another way to 'replace' something

wow and if the input file has 1000000000 lines, are you going to key in a batch file with 1000000000 echo lines ?

The whole idea of text processing in batch files has now been explained exhaustively in about 6 different ways, and I would have thought that if a person had not "got" it by now, it would be time to find a less taxing hobby.

Is there any command that can alter/manipulate text? If I get that, then I'll start with some easy, like adding a 1 to the end of each file. Like this:

Before:-

apples
pears
ADD

After:-

apples
pears
ADD
bananas

Adding a line of text to the end of a file is easy.  If your file is named food.txt, then your code would be:

Code: [Select]

echo bananas >>food.txt

[Carbon Dudeoxide]

Code: [Select]

echo bananas >>food.txt

LOL funny.
That code puts the text at the end of the file you want to edit.

Finally...

Adding - Can do
Replacing whole file - Can do (so many echos... )
Deleting

I just made something that deletes a file if it exists, then add lines to the new file (like what Carbon Dudeoxide did, but it adds the output of my batch file).


I'm going to start making something that deletes all text after a specified line.
