I have a script in Korn shell that creates a file of unique entries from a source file using the sort command below. I then count the number of times an entry appears in the source file with grep and wc.

Are there similar commands in Perl to uniquely sort an array, produce a new array and count how many times an entry appears in the original?

All I've found is a standard sort. 

@modlist2 = sort (@modlist);

Parts of Korn Shell script: 
sort -u modtype_2430.srt > modtype_2430.unq

for k in `cat  modtype_2430.unq`
do
if [ "$k" != 0 ]
then
type=$(grep $k modtype_2430.srt|wc -l)

Edit by tye, add formatting
