awk script to compare and insert a line
Hi
I want to compare a string at fixed position 10-20 for all the lines starting with 6. if they dont match it should take a copy of a line starting with 1 and insert it before the line starting with 6. How do i this? Please help

Eg

1 test 1 765533 7643743
6 yes 3 5363653 373833
7 323323 4343434435 545
8 4345435435 5454545 55
7 323323 4343434435 545
6 yes 3 5373653 373833
7 323323 4343434435 545
8 4345435435 5454545 55
6 yes 3 5373653 373833
7 323323 4343434435 545
8 4345435435 5454545 55
6 yes 3 5383653 373833
7 323323 4343434435 545
8 4345435435 5454545 55

so the output should be

6 yes 3 5363653 373833
7 323323 4343434435 545
