Hi Monks, I have two txt files, i need to compare a particular column (column 1) of numbers between each file and return the unique numbers. 
file1
6.66 6.75
6.75 6.66
6.75 6.75
7.17 7.17
7.31 7.31
7.41 7.41
 

file2
6.75 6.66
6.75 6.75
7.17 7.17
7.31 7.31
7.41 7.41

So here 6.66 would be returned? Thanks
