    You are not counting the extensions ?

    IBIZA desentol /tarifa1/users/desentol/mlima/dados/input > ls | grep - +oE "\.\w+$" | sort -u grep: illegal option -- o usage: grep [-E | -F] [-c|-l|-q] [-insvxbhwy] [-p parasep] -e pattern_ +list...

[file...] usage: grep [-E | -F] [-c|-l|-q] [-insvxbhwy] [-p parasep] pattern [fi +le...]


      GNU grep 2.5.1 has the -o option to output only the matched text. Your grep doesn't.

      As for counting...

      E:\tmp>ls | grep -oE "\.\w+$" | sort -u | wc -l 12



        You are counting to everything and not each extension !?
