Hello,

Following may help.


Code:
awk 'NR==FNR{a[$2];next} ($2 in a) {print $0}' file2  file1

Output will be as follows.


Code:
comp100001_c0_seq1      At1g31340       30.40   569     384     11      3       1673    313     834     7e-62    237
 comp100003_c0_seq1      At1g35370_2     35.00   80      50      2       597     364     678     753     1e-09   42.7


EDIT: What is the logic to get the last column data in your expected Output. Sorry I have noticed just now the last column.


Thanks,
R. Singh

The last column is the name corresponding with col2 of input 1 which is at the last header at the top starting with [some alphabets] some description.

So for At1g31340 it is [OR] Ubiquitin and ubiquitin-like proteins and for At1g35370_2 it is [R] KOG0017 FOG: Transposon-encoded proteins with TYA, reverse transcriptase, integrase domains in various combinations.

Please note that names for some ids may not be found. they should be left as it is, that is no name is added to the last column.

Here is an awk program based on some assumptions:
Code:
awk '
        NR == FNR {
                if ( $0 ~ /\[[A-Z]*\]/ )
                        D = $0
                else
                        A[$NF] = D
                next
        }
        $2 in A {
                $0 = $0 FS A[$2]
        }
        1
' input2 input1
