Batch counting number of lines of text file without blank -


i got 2 text files different formats,let says have known there 4 non-empty lines in file,shown below (1st valid, 2nd invalid).

aaa

bbb

ccc

end

(blank line)

(blank line)

aaa

bbb

(blank line)

ccc

end

any "for loop" implementations/ways distinguish 1st file has 4 non-empty lines can tell it's valid , 2nd file has blank line in middle can tell it's invalid.

because got loop code can count non-empty line number,applying code in 2 files,it gives me line number=4,which don't want cause 2nd file invalid format. for-loop code

        set count=0         /f %%a in (%text_file%) set /a count+=1         echo %count%

any suggestion identify 2 files using lines-counting method?

or can tell me how count number of lines starting until critical string "end",thanks in advance^.^

for /f "tokens=1 delims=:" %%i in ('findstr /n "^end$" %text_file%') set endline=%%i echo %endline%

this finds linenumber of (last) line, equal <startofline>end<endofline>
