Batch File Counter in a for loop

Question

I have a for loop that I'm trying to count each loop however this loop echo's zeros. How do I get it to increment?

@echo off
setlocal enableextensions

set /a count = 0

for /f "Delims=" %%a in (content\docs.html) do (
    set /a count+=1
    echo %count%
)

Have a look a this post: http://stackoverflow.com/questions/7522740/counting-in-a-for-loop-using-dos-batch-script. The problem is that `%count%` is evaluated before execution so it will always be zero, see the other post for a solution for this. — Alex, May 23 '15 at 16:01

@echo off
setlocal enabledelayedexpansion

set /a count = 0

for /f "Delims=" %%a in (content\docs.html) do (
    set /a count+=1
    echo !count!
)

notice the ! instead of %. that's the consequence of using setlocal enabledelayedexpansion.

Should be `setlocal enableextensions ENABLEDELAYEDEXPANSION` – JosefZ May 23 '15 at 18:32
works if i use 'setlocal enabledelayedexpansion' Joe. – Jahwi May 23 '15 at 19:33
Although _Command Extensions_ are enabled by default allegedly, no one could presume and confide that those are enabled _in effect_... – JosefZ May 23 '15 at 19:51
why don't we all just move to powershell then? – Jahwi May 23 '15 at 20:37
