I would use:
tar cf - . | dd obs=20k | rsh coma "cd blubber && tar xf -"
The second dd contributes nothing.
The "&&" prevents you from extracting a whole mess of stuff in the
wrong directory should you "fat-finger" the target directory.
(Leaving the '.' off the tar sends an empty archive... you gotta send
at least *something*. :-)
I also usually leave off the first dd, because tar writes its stuff
20*512 bytes at a time anyway.
If I'm nosy, it comes out as:
tar cf - . | rsh coma "cd blubber && tar xvf -"
so I can get a progress report. Run it in a separate window (GNU
Emacs or bitmap window, take yer pick).
Just another tar baby,
