on, say, a 5GB log file?..

If I read this correctly (http://www.ruby-doc.org/core/classes/IO.html#M000914) it'll read the whole file into an array, then spit out last 10 entries?

Yes it does - good point, but the sigil-tastic snippet in the parent reads the whole file into an array, too - it's just harder to tell.

Plus the parent snippet is not Ruby 1.9 compatible.

Anyways, my version was just to illustrate that sysadmin scripting in Ruby does not have illegible.
