Hello dear members,
I was wondering, how can I smartly combine 2 data files and then delete values completely which are common like In fact I want to get Data-1-Data-2 this will remove the entries of data file 2 from data file 1.
Data-1
24/25/W3 23.1 56.3
24/25/W4 25.8 56.8
24/25/W5 29.6 57.9
24/25/W6 25.2 58.4
24/25/W7 25.96 55.7
24/25/W8 30 58
and Data-2
24/25/W5 25.8 56.8
24/25/W3 23.1 56.3
24/25/W10 30 58
24/25/W6 25.2 58.4
24/25/W8 30 58
I want an output file which have both data1 and data 2 entries but no dublicates. You can see there are few same values in above example. Thanks
