scp / ssh from RedHat 7.3 used to have a '-u' switch:
from man scp:
"Makes scp2 remove source-files after copying. This makes scp2 work
more like "mv" than "cp.""

this was version:
ssh: F-Secure-SSH-2.3.1 (build 7) on i686-pc-linux-gnu

Newer sshd's seemingly no longer have this -u 'remove' option.

Anyone know where this functionality went? Is it even possible now??

I am _really_ trying to avoid a two-stage connection to duplicate this
older functionality
scp - to copy source file
ssh - to delete source file
