if you want to use python...
 

Code:

import collections
 
def remove_duplicates(inputPath:str, outputPath:str):
    values = collections.Counter(open(inputPath,'r').readlines())
    with open(outputPath, 'w') as f:
        f.writelines([k for k,v in values.items() if v == 1])
       
infile = 'yourFile.txt'
outfile = 'dedupedFile.txt'
remove_duplicates(infile, outfile)
