a,b,c is just a placeholder. It can be anything; wrt the OP, it is the same as
field1,field2,field3,field4

Just wondering how we can append tabs at the end of each line...
Data:

Append tab on field3 and field4 for the first row..and
Append tab on field4 for the second row.

Not quite sure what you're saying, but assuming you have a datafile that contains:

1 2 3 4 5
1 2 3 4 5
1 2 3 4 5
1 2 3 4 5

and you want it formatted as you've shown, you could do:
awk '{print $1, $2"\n"$3, $4, $5"\n\n"}' <datafile>

to get:
1 2
3 4 5

1 2
3 4 5
etc.

The above could also be accomplished with "awk '{printf}'".

I can't see the usefulness of adding tabs to the end of each line unless you plan to paste a file to this one, but you can do:
sed 's/$/[press TAB button here]/' datafile > newfile
