Ok the essence of this problem is that moving directories across volumes is not
the same as moving directories within a volume.
If you move a directory and it stays on the same virtual disk, then all UNIX is
doing is deleting one entry in a directory and adding that same entry into a
different directory.
If your move is actually across volumes then all the contents have to be copied
and then the original deleted. The safest way to do this is using
cp -R directory1 directory2
*inspect results
rm -R directory1
I believe that there is a mv -R command also, but it will essentially be doing
the two commands I listed above but with out the ability to return to a known
state if for some reason part of the move failed.
The other comments about checking quotes are important also, though I believe
the tab completion in bash will automatically add quotes if necessary.
Best wishes,
Jonathan Cohn
