Hi all.

I have a question, which is quicker when reading large files line by line... this one: 

#!/usr/local/bin/perl

open (IN, "/text.txt");
while (<IN>){
    if ($_ =~ /hello/){
        # do what ever
    }
}
close IN;

[download]
---OR--- 
#!/usr/local/bin/perl

open (IN, "/text.txt");
@lines = (IN);
close (IN);
foreach (@lines){
    if ($_ =~ /hello world/){
        # do what ever
    }
}

[download]

Just wondering if the file size is > 100meg and was entirely text
