no "defrag" in Linux?

Thanks Alexander, but the answer came into the forum while I was typing
my reply so I didn't see it in time.  Actualy it would have been a
little more helpful to give a bit more info than just the single word
"tune2fs", which meant nothing to me until I looked further.
Now I know, it's very useful, but please don't make assumptions that
everyone is fully aware of all the terminal commands and utilities
available to us.
