I am not sure I understand your points - so to clarify:
listing above was posted as pseudo code and not the actual code run - for $string1 and $string2 in the test case I put the literal strings of interest in place (and have updated to illustrate) I used what I found interesting for my specific situation and I left it generic when posting the code example above because I thought that would be more useful - I understand your point re: my $str... and now that works properly if I use your qr update (and I get the same times). This is not a useful or valid benchmark? my input file was:
since diff boxes have different performance depending on input_files, strings, mem., proc. etc - I guess it is better to list relative results instead of specifics ... is it just luck that your results confirm the general reason I posted, that lookahead grep is the fastest (accurate) solution? In reply to Re^4: grep for lines containg two variables
