roctaiwan,

What you want to do is place the commands in a script that sends the output to background.
make sure you have defined the environment variables referenced also.

eg: the following script starts slon for node 1 

script name: start_node_1_db.sh
contents:
------------------------------------------------------------
slon -d1 -pslon_node_1.pid $SLONY_REP_SCHEMA "dbname=$MASTERDBNAME user=$REPLICATIONUSER host=$MASTERHOST port=$PGPORT" > slon1.log &

I had following instructions of a forum on how to start replicating my first
DBs. But it has not teach me how to do submit some general commands. I have
few that I would wants to know. 

Instruction says: 
% slon sql_cluster "dbname=contactdb user=postgres" &
% slon sql_cluster "dbname=contactdb_slave user=postgres" &

Questions: 
should I type this one by one and press ENTER after the "&"?

I start from the first cluster, once it started it looks like is showning
the status log of the slony in the window
http://www.nabble.com/file/p24528069/slony_Ma_start.jpg , it just keeps
rolling and rolling, I had wait for about a min but it don't seem will stop.
For me to start my second cluster engine, I had ignore it and continue type
my second command even it would moving my lines to different line, and press
enter. But I am not sure if I had started it or not. 

How can I put these status in the back ground so I can continue doing my
thing. Also how could I put it back to screen front if I want to see it
again?
I was trying to do ctrl+c, I am not sure if I did that will I stoped the
replication process?
what is the command to see the status of all my clusters (cluster1,
cluster2, cluster3) status if its "stoped" or "started" ? 
Also whats the command to show me the detail status of clustering on every
cluster to identify if there is any problems during replicating process ?
How do I stop, start and restart the slon replication engine ? 

If I would wants to know more useful commands like those I asked, could you
referral me some places? I know www.slony.info is one place, but the
information up there is just kinda hard to absorb.
