Shell Programming and Scripting

need to login 4 systems to check whether the systems are accessible or not using rlogin command,after each login i will exit.After issuing the command rlogin abc if it is not responding i will get a message of "connection timed out" . So i want to automate this task .so i tried like below :
EX:

Code:

rlogin abc <<EOF
 6
 EOF
 rlogin xyz <<EOF 
    n     
6
 EOF
 rlogin  pqr <<EOF     
6     
EOF     
rlogin klv <<EOF 
    n
 6 
    EOF

But how can i check if the system responds or not.

When i do

Code:

 rlogin abc

and the system throws an error

Code:

"Connection Timed out "

then i want it as notification through mail. else it should continue with the process.

Any help greatly helps me

You can put other commands after the beginning of a here document <<string as long as they're on the same line. You can extend "same line" with backslashes at the end of the line.

Code:

command 2>&1 <<EOF | another command | another command
text
that
gets
fed
into
first
command
EOF

I don't understand your code, I suspect it got stripped of newlines or otherwise garbled. Please post code in code tags.
