About Finding Batch Labels using FINDSTR

#1 Post by Meerkat » 20 Dec 2015 10:57

Hi again guys!

Assuming the quirky rules from http://www.dostips.com/forum/viewtopic.php?f=3&t=3803 are not in my batch file (Only whitespaces are present), how can I detect batch labels using FINDSTR?

For instance, (Sample.bat)

Code: Select all

::Intro comments
::Blablabla
::Yeah!!!
::Blablabla

@echo off
   ::Comment again
   goto :main

   ::Some codes here...

   :main
   ::Some code here
   echo This is some piece of code...

   :thisisalabel
   ::this is a comment...
pause
exit /b

From my young intuition, I tried to use this FINDSTR command:

Code: Select all

>findstr /r ":[^:][^:]*" Sample.bat

I expect that only :main and :thisisalabel will appear, but the output became:

Code: Select all

::Some comments
::Blablabla
::Yeah
::Blablabla
        ::Comment again
        goto :main
        ::Some codes here...
        :main
        ::Some code here
        :thisisalabel
        ::this is a comment...

What is wrong with my FINDSTR? :| Thanks a lot guys! :D

   :main
   :thisisalabel
