thanks a lot.. i have figure it out by using "paste" command.. it really works

paste -d "\0" unp_bef60.fa unp_bef60-2.fa > unp_bef60_dup.fa

here,

unp_bef60.fa original fasta file
unp_bef60-2.fa is same file with another name..
unp_bef60_dup.fa is final file after duplication..

just need to remove duplicated headers which is an easy task.
