Thanks for the inspiration amrangaye! :-)

But when I kaeps sdrawkcabs I don't speak entire sentences sdrawkcab... just each word.

So here is my version

perl -ane 'foreach $F (@F) {print scalar reverse $F, " ";}'
[download]

thereby picking each word out of the auto @F array and reversing it, but preserving its order in the overall line.

the thing I dont like about it is, it eats line feeds...
