You cannot use == on a list of numbers. It will check if column 7 is equal to "1234 1235", see that it isn't, and return false. You'll have to split it in the BEGIN section. If you put it in an array like B["12345"]=1, you can check without a loop.

Since you need it in the BEGIN section, you will have to put the variable in with -v before, not VAR= afterwards. When you put in variables at the end, they get assigned when awk starts reading files, after BEGIN happens.

Code:
awk -v N="1234 5678" 'BEGIN { split(N,X); for(L in X) B[A[X]]=1 } $7 in B' inputfile

Test::use::ok(3)					User Contributed Perl Documentation					  Test::use::ok(3)

NAME
Test::use::ok - Alternative to Test::More::use_ok SYNOPSIS
use ok 'Some::Module'; DESCRIPTION
According to the Test::More documentation, it is recommended to run "use_ok()" inside a "BEGIN" block, so functions are exported at compile-time and prototypes are properly honored. That is, instead of writing this: use_ok( 'Some::Module' ); use_ok( 'Other::Module' ); One should write this: BEGIN { use_ok( 'Some::Module' ); } BEGIN { use_ok( 'Other::Module' ); } However, people often either forget to add "BEGIN", or mistakenly group "use_ok" with other tests in a single "BEGIN" block, which can create subtle differences in execution order. With this module, simply change all "use_ok" in test scripts to "use ok", and they will be executed at "BEGIN" time. The explicit space after "use" makes it clear that this is a single compile-time action. SEE ALSO
