"\n"; In my Learning Perl 2nd edition and Programming Perl 3rd edition, no where does it say use scaler @fa to get the element count, rather it says use $#fa. Is there something I am unaware of or was $# deprecated recently? Why is scaler @fa better/more correct than $#fa? I have been told that my @a = ( ); is more correct than my @a, but now I am confused b/c others are telling me otherwise??? Personally, I like my @a = ( ); because it lets me know explicitly that this array is now initialized to 0 elements, plus its faster at compile time...KUDOS to John Kran! >From Jupiter : > > You do realize that the characters 'F', '0' and '1' are included in the > character class \w which split() is removing? :-) yeah I realized that typo too late :), I meant \s not \w but then plain old my @tmp = split; is even better :) But I thought spit by default separates on whitespace? And F, 0 and 1 are indeed apart of char classes \w and \d? Finally no one has answered my question what does (split)[-1] mean? thank you! derek Derek B.

You only want the two columns, that looks simple enough: while ( <V4> ) { my ( $percent, $f01 ) = /(\d+%).*?(f01\d+)/i or next; print "$percent $f01\n"; } > 1 2005/01/20 15:39 17 2% -il-o-b- - - - - sg F01000 > 2 2005/01/20 15:53 14 1% -il-o-b----- sg F01001 > 3 2005/01/18 09:53 2 0% -il-o-b----- sg F01002 > 4 2005/02/04 16:41 196 100% -il-o-b----f sg F01003 > 5 2005/02/05 21:13 305 100% -il-o-b----f sg F01004 > 6 2005/02/28 22:47 180 100% -il-o-b----- sg F01005 > 13 2005/02/08 16:07 112 100% -il-o-b----f sg F01006 > 14 2005/02/09 21:56 122 100% -il-o-b----f sg F01007 > 15 2005/02/11 10:51 147 100% -il-o-b----f sg F01008 > 16 2005/02/13 11:35 193 100% -il-o-b----f sg F01009 > 17 2005/02/14 23:46 79 100% -il-o-b- - - -f sg F01010 > <SNIP> John -- use Perl; program fulfillment -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] <http://learn.perl.org/> <http://learn.perl.org/first-response> -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] <http://learn.perl.org/> <http://learn.perl.org/first-response>
