Also, as there is only one thing repeated, if you actually know what it will be beforehand just use grep:

grep -c WAIT file

Re: uniq doesn't delete more than 4 lines

man uniq

"Note: 'uniq' does not detect repeated lines unless they are adjacent.  You may want to sort the  input  first, or use 'sort -u' without 'uniq'."
