bash: any way to reuse the last output?

[Herculano de Lima Einloft Neto <hlen ig com br>]

Hello all,

   This happens all the time: after an intricate find, I decide
to grep something out of that very same find, for instance. It
would be nice to have some tweak to reuse the last output without
having to run the command again. Anyone?

Thanks in advance,
