I am doing a program which works with a dbm file, but doesn't "want" all
the values it stores, so it saves a text file with a sorted array.  The
problem is that I don't see how to get rid of duplicate values (I am using
sort() to combine the file with an array read in at runtime, and there are
often duplicate values).

Is there any way to get sort() to do the equivalent of sort -uniq?  If not,
what's the best way to do it (I assume piping to sort, but I'd like
examples, as I'm still fuzzy on how to get piping to work well)?

I'm using 3.0PL18 on SunOS 4.1.
