deleting dupes in a row

Hello,
I have a large database in which name homonyms are arranged in a row. Since the database is large and generated by hand, very often dupes creep in. I want to remove the dupes either using an awk or perl script.
An input is given below
Quote:
mohammed=mohd=muhammed=mohammed=mohd=muhammed=md=muhmd
mahendra=mahendera=mahndra=mahendra=mahendera
The expected output is given below:
Quote:
md=mohammed=mohd=muhammed=muhmd
mahendera=mahendra=mahndra
As can be seen all the dupes are cleaned out.
At present I am using a macro which converts row to line, sorts and deleted dupes and restores the row structure. Since the database is huge, the macro takes a very long time.
Many thanks in advance for a speedy solution
