Hello List,
I want to copy /usr to a new partition and then attach that at /usr. I
issued a command
cp -options(recursive included) /usr /mnt/"mountpoint
This resulted in the creation of a new "usr" directory under
/mnt/"mountpoint"/usr and contents of /usr went into sub-directories.
What I want is to copy all the subdirectories and files directly under
/usr to go at /mnt/"mountpoint" for obvious reasons. How do I do that?
"Man cp" did not give me any clue.
cp never seems to do what I want, so I'd
sudo -s
tar clC / usr | tar xpC /mnt/mountpoint
which has the great merit of being easily extended to copy between machines:
tar clC / usr | \ssh otherbox tar xpC /mnt/mountpoint[1]
and of course one can compress or not.
Also, is there a command which compares each file under two directory
trees for difference.(I want to verify after the above operation)
diff

I got caught one or twice: I have set ssh to an alias:
alias ssh='ssh -t'
and that breaks piping stuff across the network. Use of the backslash
prevents use of the alias.
