Simple Perl Script to get Unique values from file

It has been a few years since I have used Perl.  I have a text file with about 400 entries.  There are duplicates in the file.  An example of the input file would be.

smith
jones
taylor
smith
bruce

I need a output file with only the unique values.  An example of the output file

smith
jones
taylor
bruce

order is not important - I just need the unique values
