which command I should use to output sequentially,

[lina <lina.lastname@gmail.com>]

Hi,

For something like

1a  O28
1a  H29
1a     C1
1a     C3
1a     C8
1a     C2
....

2a  O28
2a  H29
2a     C1
2a     C3
2a     C8
2a     C2


How can I make the output for the field 2 from C1, C2, C3... O28, H29?

but still keep the first field as 1a 2a 3a ...

Thanks for any suggestions,
