I don't think this will work (maybe depending on the shell program) as the
current working directory is in use. Bob had a problem but didn't say what
went wrong (the example below uses zsh).
and everything in /home/bobg//Public/nfs4exports/home will be moved
to /home/bobg/Public (up 2 directories). This will be fast and only
move the file headers since both locations are on the same
LV/mountpoint.
Bob: You can convince yourself that the above works by working thru
an example.
% cd /tmp
% mkdir -p a/b/c
$ cd a/b/c
$ touch d
$ ls -l
total 0
-rw-r--r--. 1 u u 0 Sep 16 16:20 d
$ mv . ../../
mv: cannot move '.' to '../../.': Device or resource busy
% cd -
/tmp
% cd a
% mv b/c .
% ls -l
total 0
drwxr-xr-x. 2 u u 40 Sep 16 16:38 b
drwxr-xr-x. 2 u u 60 Sep 16 16:20 c
% ls -l c
total 0
-rw-r--r--. 1 u u 0 Sep 16 16:20 d
% ls -l b
total 0
It ia now safe remove "b"
