I have a pattern file with the following:


Code:
chr1    1000    2000    chr1    10000    11000
chr1    1000    2000    chr1    11000    12000
chr1    1000    2000    chr1    12000    13000

For a single query, I am using the command:
Code:
awk '{if ($1 == "chr1" && $2 == "1000" && $3 == "2000" && $4 == "chr1" && $5 == "38000" && $6 == "39000") print $0}'  DB_file.txt

How can I do for all the patterns in a file ?
