Batch script to Insert all lines from a text file before occurrence of a specific string-CodePudding

I'm using below code for inserting text contents after a specific line/string is found. How can I modify this code to insert all the lines before the occurrence of line/string in file ?

@echo off
for /f "delims=:" %%i in ('findstr /rinc:"string"  test.txt') do (set line_no=%%i)
for /f "skip=%line_no% delims=" %%a in ('type test.txt') do (echo %%a >> output.txt)

i.e if test.txt contains:

abc
def
p q r
u v w
xyz

If the the search is for line p q r, the output should be:

abc
def

Test if the line matches the sting, if it does, exit loop:

@echo off
(for /f "delims=" %%i in ('type test.txt') do (
    if "%%i" == "p q r" exit /b
    echo %%i
 )
)>output.txt

To include everything up to and including the search string, simply swop the if statement and the echo lines.

@echo off
(for /f "delims=" %%i in ('type test.txt') do (
    echo %%i
    if "%%i" == "p q r" exit /b
 )
)>output.txt

as a replacement to your original code:

@echo off
set str=
(for /f "delims=" %%i in ('type test.txt') do (
    if defined str echo %%i
    if "%%i" == "p q r" set str=1
 )
)>output.txt

and to include the search string.

@echo off
set str=
(for /f "delims=" %%i in ('type test.txt') do (
    if "%%i" == "p q r" set "str=1"
    if defined str echo %%i
 )
)>output.txt

Note that this will also remove any empty lines from the original file.
