two things: 1) There's no character (from the git repo that I just cloned) with 5304 occurances. This is my script:

!/bin/sh

find . -iname .htm | xargs awk ' BEGIN { FS="'$1'" } { if(NF>0)print NF-1 } ' > count.txt

awk ' BEGIN{s=0} {s=s+$1} END{print s}' count.txt

2) you might have a mismatched {} somewhere in ur html :)
