Hi,

Please help!
I have a file having duplicate words in some line and I want to remove the duplicate words.
The order of the words in the output file doesn't matter.

INPUT_FILE
pink_kite red_pen ball pink_kite ball
yellow_flower white no white no
cloud nine_pen pink cloud pink nine_pen
brown_ball white
red_bear green red_bear
white no

OUTPUTFILE
pink_kite red_pen ball
yellow_flower white no
cloud nine_pen pink
brown_ball white
red_bear green
white no

Your help is highly appreciated.
Thanks in advance
