Hello beca123456,

As per your request each 1st field with respect to 2nd field should be less than 4, so I have taken field 2 as index and added all it's first fields(Assuming as per given data like there will be only 2 fields with values and one will be for ref) and if sum is less than 8 means we are good to add * at end else don't do anything. Now about your query to give Input_file 2 times, in awk we can read multiple files(same like we can multiple arguments to a script). It will read files one by one. Here I want to mention I have put condition FNR==NR this condition will be true only when first file will be read as FNR value will be reset to one each time it goes to read next file but NR value will be keep on increasing even file name is changed, so it will like as follows.

Code:

awk '{print FNR ":" NR}' Input_file Input_file
1:1
2:2
3:3
4:4
5:5
6:6
1:7
2:8
3:9
4:10
5:11
6:12

Notice the highlighted ones for FNR values. I hope this helps, if you have any query kindly do let me know, will try to solve.

Thanks,
R. Singh
