scottn,

thank you for your Patience.

The first solution:

Code:
cat input_file1 input_file2 etc | grep -f pattern_file

returns virtual memory exhausted :-(

The second one:

Code:
awk 'NR == FNR { p[$1]; next } $0 ~ p[$2]' pattern_file input_file*

Does not work!! It returns all the lines of "input_file". A second bad thing is that, the searched pattern is NOT always at the second position, e.g.
Code:
...
000000 abc2344536      46575 0000
000000 89798798798    abc2344536
000000 abc2344555      46575 1234
000000 7777777777     abc2344536
...

:-(
