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

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` [download]	[reply] [d/l] [select]

Ok! You are counting to everything and not each extension !? `IBIZA >ls SN10738.ksh calculo_SN10738.ksh separa_tabllama.awk SN10738.log calculo_SN10738B.ksh transferSN10738A.ksh filtroSN10738A.ksh separaVielinSN10406.ksh IBIZA >perl -e 'while(<*>){if(-f && /\.(\w+)$/){$e{$1}++}}print "$_ -> + $e{$_}\n" for keys %e' ksh -> 6 awk -> 1 log -> 1` [download] `SHELL: IBIZA >ls \| cut -sf2 -d. \| sort \| uniq -c 6 ksh 1 awk 1 log` [download] Mago mago@rio.pm.org	[reply] [d/l] [select]
