Hi.

I got a flat file of about 71KB and 500 lines. It keeps growing all the time, since it's a user database. I got some scripts that process it to authenticate users.

What would eat up less system resources? Doing a sequential scan on the file: example:

open(DB, 'one.txt') or die "Error";
while(<DB>) {
chomp $_;
if($_ eq $whatever) { $info = $_; break; }
else { next; }
}
close(DB);
Or loading it to an array, and the processing it: example:

open(DB, 'one.txt') or die "Error";
@db = <DB>;
close(DB);

foreach $i (@db) {
chomp $i;
if($i eq $whatever) { $info = $i; break; }
else { next; }
}
?

Thanks,
Ralph.
