Off topic:moving 2 columns with the same party in two files

Question

[mm]

I have two map files in the following format:

file1:

1   DU202534_254.1  0   18803224

1   DU281551_498.1  0   315497

1   DU492501_194.1  0   158758936

file2:

0  CL635944_160.1    0    0

0   CR_594.1         0    0

0    CR_816.1        0    0

0    CZ925803_293.1   0   0

The second file is going basis According to Snp ID subscribers in the first file (in the second column)

Columns 3 and 4 first file into the second file transfer at the same Snp ID's

And the remaining Snp ID to be removed.

How this is done in Linux?
