Without knowing your OS and shell there are too many possible ways.

You may try something like this (assuming POSIX shell and no embedded newlines in the filenames):
ifs=$IFS IFS='
'
set -- $(egrep -l '([^,]*,){7} *,' *)
for f in *; do
  for _f; do
   [ "$f" == "$_f" ] && continue 2
  done
  printf '%s\n' "$f" # do whatever you want with the file
done  

IFS=$ifs
On Solaris this script will work with /usr/xpg4/bin/egrep and possibly /usr/xpg4/bin/sh.

can you explain me your script my frined.
