Shell Programming and Scripting

Guys

If someone could help me? Basically I want to connect from my central server and run the script to remote servers (in our environment we do not need a username/password to connect); like below

ssh <server_name_1> /ora/rman/scripts/bk2.sh 2>/dev/null >> /tmp/an.log
ssh <server_name_2> /ora/rman/scripts/bk2.sh 2>/dev/null >> /tmp/an.log
..
..
ssh <server_name_n> /ora/rman/scripts/bk2.sh 2>/dev/null >> /tmp/an.log

I have all these servers name in one file.....so basically I need to loop through all these servers/hosts and run above command

Also while making connection to server I also want to scp my script (i.e. bk2.sh) to all these servers

Could anyone please help?

man rdist...

Code:

#!/bin/sh

while read host
do
   scp bk2.sh $host:/ora/rman/scripts/bk2.sh
   ssh $host /ora/rman/scripts/bk2.sh 2>/dev/null >> tmp/an.log
done < hostlist

Thanks; but this only works for the first server in the list...any suggestions to make it workable for all the servers in the file? And if I remove '/' from /tmp/an.log then scp works for all servers but ssh only works for the first server in the list



while read host
do
scp bk2.sh $host:/ora/rman/scripts/bk2.sh 2>/dev/null
ssh $host /ora/rman/scripts/bk2.sh 2>/dev/null >> /tmp/an.log
done < /export/home/oracle/server.lst
