Thanks everyone for you help. The one I went with was
Code:
paste -d "|" f1 f2 | awk -F "|" '
{ if ( $1=="" ) { print $2}
else {print $1}
}' > f3

thanks to Jadu Saikia

HI Protocomm,

the logic is if the number of field is greater than zero then it will print $0(which is the current line of file1 and if the number of field is zero then it will frint the second argument which is f1[NFR].


a?b:c
it mean if a is true then excute b else excute c

regards,
Sanjay

as long as your two files contain same number of rows, below one should be ok.

Code:
paste -d"," f1 f2 | awk -F"," '{if($1=="") print $2; else print $1}'
