Thanks for the reply basically the problem is that I do not need most of the fields contained in file 1 and most of the fields in file 2 Few lines of file1:
169: rs60465173 has merged into rs8057341 Homo sapiensCAGCTGACTGAGGCAGCGGGAGTTGAA/GAAGAAACGATATTAGTTCATGGTGA ABI, AFFY, ILLUMINA-UK, ILLUMINA, ILLUMINA, ILLUMINA, ILLUMINA, ILLUMINA, ILLUMINA170: rs17312781 has merged into rs8057341 Homo sapiensCAGCTGACTGAGGCAGCGGGAGTTGAA/GAAGAAACGATATTAGTTCATGGTGA ABI, AFFY, ILLUMINA-UK, ILLUMINA, ILLUMINA, ILLUMINA, ILLUMINA, ILLUMINA, ILLUMINA171: rs8057341 Homo sapiensCAGCTGACTGAGGCAGCGGGAGTTGAA/GAAGAAACGATATTAGTTCATGGTGA ABI, AFFY, ILLUMINA-UK, ILLUMINA, ILLUMINA, ILLUMINA, ILLUMINA, ILLUMINA, ILLUMINA172: rs60162986 has merged into rs8046608 Homo sapiensCCCTACTTACTTGTGGCCTGTCCCCTC/TGTGAATGTGTCTCATGTCCCCAGTG AFFY173: rs8046608 Homo sapiensCCCTACTTACTTGTGGCCTGTCCCCTC/TGTGAATGTGTCTCATGTCCCCAGTG
From there I need the rs value. And for this I made the code I wrote about. Now I have rs values in an array and I need to grab only the lines which contain the rsnumbers from a second huge txt file (1 GB) The second file looks like


First row XXX XXX XXX XXX XXX XXX XXX XXX (1050 cells)

rsnumber AA AG AG AG AA AG AG AG (1050 times)

rsnumber TT AT AA AT AT .....

500 times more
I need to get from this file the rsnumbers stored in the array from file 1 toghether with the 1050 values on the string
