How to count no of lines in text file and store the value into a variable using batch script?

Question

I want to count the no of lines in a text file and then the value has to be stored into a environment variable. The command to count the no of lines is

findstr /R         


        

Answer 1

You don't need to use find.

@echo off
set /a counter=0
for /f %%a in (filename) do set /a counter+=1
echo Number of lines: %counter%

This iterates all lines in the file and increases the counter variable by 1 for each line.
