Using awk is what you are doing wrong ;-) Assuming that this is all you 
are doing with the list, anyway...

 From the grep manpage:
"       -l, --files-with-matches
              Suppress  normal  output;  instead  print the name of each 
              file from which output would normally have  been  
printed.   The
              scanning will stop on the first match."

The awk answer is that the printf shouldn't be in the BEGIN section, I 
think. It's been a while for me and awk though. Something more like:

BEGIN { FS = ":" }
      {  printf("%s\n", $1) }

would do it. Also see cut(1) which can select fields based on delmiters. 
I don't know if the traditional perception of 'heaviness' associated 
with loading a 'real language' interpreter really hold true nowadays though.

Have fun!
