You need the textFX plugin   Then  just follow these instructions   Paste the text into Notepad    CTRL V       Mark all the text  CTRL A       Click TextFX   Click TextFX Tools   Click Sort lines case insensitive  at column  Duplicates and blank lines have been removed and the data has been sorted alphabetically    Personally  I would use sort -i -u source  dest instead of notepad

If it is possible to change the sequence of the lines you could do    sort line with Edit -  Line Operations -  Sort Lines Lexicographically ascending do a Find   Replace    Find What       r  n  1  Replace with   Nothing  leave empty  Check Regular Expression in the lower left Click Replace All    How it works  The sorting puts the duplicates behind each other  The find matches a line      r  n  and captures the line in  1 then it continues and tries to find  1 one or more times     behind the first match  Such a block of duplicates  if it exists  is replaced with nothing    The  r  n should deal nicely with Windows and Unix lineendings

You could use      Click TextFX   Click TextFX Tools   Click Sort lines case insensitive  at column    Duplicates and blank lines have been removed and the data has been sorted alphabetically    as indicated above  However  the way I did it because I need to replace the duplicates by blank lines and not just remove the lines  once sorted alphabetically   REPLACE           n      k lt 1 gt    by   3   This will convert   Shorts Shorts Shorts Shorts Shorts Shorts Two Pack Shorts Two Pack Signature Braces Signature Braces Signature Cotton Trousers Signature Cotton Trousers Signature Cotton Trousers Signature Cotton Trousers Signature Cotton Trousers Signature Cotton Trousers Signature Cotton Trousers Signature Cotton Trousers Signature Cotton Trousers Signature Cotton Trousers Signature Cotton Trousers   to   Shorts  Shorts Two Pack  Signature Braces           Signature Cotton Trousers   That s how I did it because I specifically needed those lines
