Batch script that counts how many times a string appears in a file

This simple example will count how many times a specified string appears in a file.

Code:

@echo off
 setlocal

set str2find=world
set file=%~1
set token=0

for /f "tokens=*" %%- in (%file%) do (
    set str=%%-&&call :NEXT
)
goto :COUNT

:NEXT
for /f "tokens=1,*" %%a in ("%str%") do (
    set str=%%b
    set strfind=%%a
)
if /i "%strfind%"=="%str2find%" set /a token=%token%+1
if "%str%"=="" goto :eof
goto :NEXT

:COUNT
echo.%str2find% was found %token% times.

 

What the use of it??

 

Its pretty self explanatory.
Don't troll me because you have nothing better to do.

You are asking questions about 8085 processors and assembly language and you can't understand what this simple little batch script does.
Yes you are trolling me in a very childish manner.
