Hello,

I have a file like the following

ID1 ch1 70 mir abc xyz ch2 2050

ID2 ch1 90 mir abc xyz ch2 4000

ID3 ch1 100 mir abc xyz ch2 2045

ID4 ch1 120 mir abc xyz ch2 2025

I need to sort the last column and after sorting if the difference between first and last element is >=500 (in this example second line) that should be omitted and remaining three lines should be printed.

Output should be:

ID1 ch1 70 mir abc xyz ch2 2050

ID3 ch1 100 mir abc xyz ch2 2045

ID4 ch1 120 mir abc xyz ch2 2025

Any help in this task will be appreciated.

Thanks in advance,
