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

Thanks to all, I've learnt a lot.

In my rush to try the code suggested by choroba, I failed to notice the second step, i.e. system sort, duh!.

I've tried it now and it seems good for my purposes - I liked that it seemed to be able to use all cores (showed 99% CPU usage, versus 12% for perl.exe which I assume is just one of my 8 cores). I'm off now to learn more about the sort command - I need it to recognise tab separation.

For sort, columns are whitespace separated. If you want only tabs, use something like `sort -t $'\t'` [download] (the bash way). لսႽ† ᥲᥒ⚪⟊Ⴙᘓᖇ Ꮅᘓᖇ⎱ Ⴙᥲ𝇋ƙᘓᖇ	[reply] [d/l]
