9:jhhh 12.12.AF.12

This is not working if the infile has:

Code:
echo "Hai........"
abdfkljk 110.111.111.11 kjdkjjkjdk
11.11.1.1111
3.23.AS.AA
24.DD.DD.DDD
24.DD.DD
24.DD.DD.EE
ab.cd.df.rf
/usr/bin
jhhh 12.12.AF.12

Output is
Code:
10:jhhh 12.12.AF.12

whereas Output should be

Code:
7:24.DD.DD.EE
10:jhhh 12.12.AF.12
