Help with rename header content based on reference file problem
I got long list of reference file
Code:
>data_tmp_number_22
>data_tmp_number_12
>data_tmp_number_20
.
.

Input file:
Code:
>sample_data_1 Math, 5, USA, tmp
SDFEWRWERWERWRWER
FSFDSFSDFSDGSDGSD
>sample_data_2 Math, 15, UK, tmp
FDSFSDFF
>sample_data_3 Math, 50, USA, tmp
ARQERREQR
.
.

Desired output:
Code:
>data_tmp_number_22
SDFEWRWERWERWRWER
FSFDSFSDFSDGSDGSD
>data_tmp_number_12
FDSFSDFF
>data_tmp_number_20
ARQERREQR
.
.

My purpose just wants to replace all the input file header becomes the header of reference file.
Any programming language will be appreciated.
Thanks.

Code:
cat Input_File | paste - Ref_File - | awk '{print $2RS$3}'

Code:
# cat input
>data_1
SDFEWRWERWERWRWER
>data_2
FDSFSDFF
>data_3
ARQERREQR

Code:
# cat ref
>AAADF
>RTHQ
>FDSF

Code:
# cat input | paste - ref - | awk '{print $2RS$3}'
>AAADF
SDFEWRWERWERWRWER
>RTHQ

thanks, ROHON.
I just edit my post with another example.
Do you have any idea to solve the problem?

is there any particular defined patterns of header and other lines in input file, so that I can recognize whether line is a header or a normal line?

If lines in inputFile to be replaced always starting with character > then:
Code:
awk 'NR==FNR{a[NR]=$0;next;}{if(a[i] && substr($0,1,1)==">"){$0=a[i];i++;}print;}' i=1 codeFile inputFile

This will replace all lines in inputFile which starts with charater >
