Hi:

You could do:

# perl -nle '$x{$_}++;END{for $val (sort keys %x) {print join "=",$val,$x{$val}}}' file

...which using your data gives:

TKTGRS8028=5
TKTGRS8263=12
TKTGRS8439=1

In posix-shell or ksh, it would be a little more convoluted and not as elegant as JRF's perl solution but here it is:

for i in `cat T3.lst|sort|uniq`
do
ct=`grep "$i" T3.lst|wc -l`
echo "$i = $ct"
done

a simple:

sort T3.lst | uniq -c

produces:
5 TKTGRS8028
12 TKTGRS8263
1 TKTGRS8439

which may (or may not) suffice for your needs.

SEP: While that gives you unique entries, the last line of the original post requests counts of each (at least thats how I read it)
