This would likely be the most memory efficient, as you'd never need a second copy of the input in memory.

</div>Does the process require the presence of the entire file in memory before<br>
the loop, and the shuffled-down file afterwards? Do you output the<br>
remaining lines?<br></blockquote><div><br>No, but I need to output the 'remaining' lines.<br><br>Also I forgot to mention, the reason the original data was in an array, was because<br>it came from one of two sources... slurping a file, or a 'received' string.<br>
So I thought I'd first normalize either dataset into the array I would then traverse.<br></div></div><br>
