First of all, you need to understand what the '*' and '?' characters are
doing for your line, how, and when.
When you type a command and hit <ENTER>, the shell will 'glob' the command
before it passes it to the interpreter.
What that means is that 'what you see' is NOT 'what you get'.
You can read about it in:
http://en.wikipedia.org/wiki/Glob_(programming)
Then inspect what glob(ing) will do for you, try:
echo /home/* # <= NO QUOTES!
You can have as many arguments as you want on an 'rsync' (or cp) command,
which implies that everything will be copied to the last directory (RTFM).
If you have directories
/home/xyz1
/home/xyz2
/home/xyz3
/home/xyz4
/home/xyz5
And you say:
rsync -a /home/xyz*
this will 'glob' to:
rsync -a /home/xyz1 /home/xyz2 /home/xyz3 /home/xyz4 /home/xyz5
which will copy the content of the directories /home/xyz{1.2.3.4} to
/home/xyz5
Probably not what you expected... (or wanted)
When you say:
<user2>@address2>/home/xyz*
You intent to 'glob' the remote directory, but 'glob' will happen before the
line is executed and the remote box will be unavailable then, so it will
'glob' the local box and (if you are lucky) you'll get an error (if you are
unlucky you'll break something)
Finally look at the rsync syntax and then break this line:
> rsync -aHv <user1>@<address1>:/home/xyz*/ /home/xy* <user2>@address2>/home/xyz*
into components...
See if the components will fit the syntax (they won't).
Remember, for every problem there is always an obvious, direct and wrong
solution.
Watch your step...
