Re: how can we read each line from a file onto an array?

my @lines = <FILE>
[download]

above loads the whole file at once in memory.

Instead, you can do something like


while(my $line=<FILE>){
  do_something;
}

This code will still traverse the whole file, so wont be faster but it will load only one line at a time in the memory - helpful if you want to parse 4GB file and have only 2 GB RAM ;)
