Hi All,

Okay, I need help.
I need to ssh in to multiple linux servers execute certain commands and get them to email and print on the screen when the script is being executed.
So below is my script. Its not working :-(.

Code:
#!/bin/bash
#linux/UNIX box with ssh key based login
SERVERS="1.2.3.4"
# SSH User name
USR="abc"
 
# connect each host
for host in $SERVERS
do
ssh $USR@$host
mail -s "1234" abc.xyz@mmmm.com
echo "in centos" 
exit
done

It does prompt for password after entering the password It will enter the appropriate server and wait for some commands to be given Smilie...

I wanted it to go ahead and execute the below mail and echo commands.

NAME
ssh-argv0 -- replaces the old ssh command-name as hostname handling SYNOPSIS
hostname | user@hostname [-l login_name] [command] hostname | user@hostname [-afgknqstvxACNTX1246] [-b bind_address] [-c cipher_spec] [-e escape_char] [-i identity_file] [-l login_name] [-m mac_spec] [-o option] [-p port] [-F configfile] [-L port:host:hostport] [-R port:host:hostport] [-D port] [command] DESCRIPTION
ssh-argv0 replaces the old ssh command-name as hostname handling. If you link to this script with a hostname then executing the link is equivalent to having executed ssh with that hostname as an argument. All other arguments are passed to ssh and will be processed normally. OPTIONS
