Removing duplicate lines from a text file

I have a text file (attached) that has duplicate lines in it. How would I remove those lines?

[Walter Roberson]

read the lines of the file. use unique(TheLinesCell, 'stable') and write the results out to a new file.

There are several ways to read the lines. See fgetl() for one way.

Do you by any chance still have the code for this?
