Hi All,

How to load bulk of records from one file to another file.Is there any memory allocation techiques available.Need suggestion in that....

Eg:
just reading the data from the file and changing some value and storing into another file .. It's happening for record by record .. But i want to insert bulk of record at the same time.


any response appreciatable..

What do you want to achieve? If memory consumption is a concern, line by line appending is preferrable.

You can always do:

open my $f1, '<', 'file1' or die "Couldn't open file1: $!";
open my $f2, '>', 'file2' or die "Couldn't open file2: $!";

while ( read $f1, my $tmp, 131072 ) {
	$tmp =~ s/OLDVALUE/NEWVALUE/g;
	print $f2 $tmp;
}

OTOH, that does not prevent "some value" from being split between two chunks...
