And if you don't:

Code:
awk '{$1=$1}; /^ABC/ { print P; P=$0; next }; { P=P " " $0 }; END {   print P }' OFS="\t" data

ABC     123456  abcde   987 890456      7890    xyz ght gtuv
ABC     5tyin   1234    789 ghty        kuio
ABC     ghty    jind    1234 678        ght

Partially Successful.
Thanks Corona688. This gives the desired output for the given input, it insert a blank line as first record.
Also this is not working if ABC comes as field other than first. I need to consider ABC as delimiter only if it comes as first field of the line.
For example

Code:
ABC 123  xyz ABC 678
ftc 345
ABC rty gty
567 778

I need output as

Code:
ABC 123  xyz ABC 678 ftc 345
ABC rty gty 567 778



but I get the output as

Code:
ABC 123  xyz 
ABC 678 ftc 345
ABC rty gty 567 778

Please reply.Smilie

Sorry Corona688. It worked successfully. I made a mistake in the data.
The exception is output is started with blank line.

Thanks a lot.
