[chomps303]

I have a file with multiple fields that have the same info.
How can I get a count of UNIQUE strings.

Thanks

Hi.

uniq <yourfilename> |wc -l

counts unique strings (at least on AIX).

SCO v5.07 also has uniq! Never knew that

uniq is for sorted file.
You may try sort -u

Hope This Helps, PH.
