Re: What is the most memory efficient way to (sort) and print a hash?

Use each to print the hash:

while (my ($k, $v) = each %hash) {
    print "$k\t$v\n";
}

Then pipe to shell's sort -k2n.

Many thanks choroba. That prints the hash with no further memory usage which helps a lot. If you, or others, can suggest a better way to get sorted output then that would be a bonus.	[reply]

That prints the hash ... a ... way to get sorted output ... would be a bonus. So, what happens if you then actually (system) sort the output per choroba's original suggestion?	[reply]

Define 'better' in relation to the suggested answer. There are trade-offs whether you use this solution or another, e.g., using a database as suggested elsewhere in this thread.	[reply]

File::Sort rather than `system "sort"`?	[reply]
