Batch file

How do I set up a variable that stores the results of this command:

findstr /R /N "^" c:\folder\file.txt | find /C ":"

The command counts the number of lines in a text file.

The goal is to check the number of lines in the text file and if more than 2 lines then continue processing but if less than 2 lines than do nothing.

Thanks for looking! Anything will help.  I'm completely okay if it doesn't work this way but any suggestion or input would be very much appreciated.

In a dos/cmd window:
for /f "delims=" %a in ('findstr /R /N "^" c:\temp\usbit32.txt ^| find /C ":"') do @set somevar=%a
echo %somevar%

Open in new window


Then use %somevar% to test for amount of lines.
If you put the above in a batch file, then use %%a instead of %a, like this:

@echo off
for /f "delims=" %%a in ('findstr /R /N "^" "%1" ^| find /C ":"') do @set somevar=%%a
echo "%1" has %somevar% lines

Open in new window

(save the above as lines.cmd)

C:\Temp>dir log.txt
