Aren't you in server1 already? Or if not, why not ssh to server1 directly?
Code:
echo $HOSTNAME
sleep 1
I had to add the 'sleep 1' because, without it, it ran and quit almost instantly, too fast to see. It works otherwise.
(i) I cant ssh directly to that server. I have to login to a main server. From there i can ssh to any server
(ii) IF the command contains ssh server1 and then other commands, it just logs in to the server1 and it just sits there. Instead, if i just try to run a script ( from the main server) directly by including it in commands.txt , it quits instantly . Ill try including sleep command after running the script. Can you also tell me how to store the output of the script into a variable in command prompt.
Actually i have to store value of the script output in DOS command prompt variable i.e. the command line logs into putty runs the script and then outputs the result to a variable which i can then utilize. Currently while running the following command it runs the script displays the value and exits after 100 seconds.

PUTTY cannot do that. PUTTY is graphical, and displays the result graphically.
The plink utility I mentioned earlier is non-graphical, and prints to the CMD prompt, which you can capture with for -- for is a very, very versatile word in Window CMD.
Code:
c:> plink
PuTTY Link: command-line connection utility
Release 0.61
Usage: plink [options] [user@]host [command]
("host" can also be a PuTTY saved session name)
Options:
-V print version information and exit
-pgpfp print PGP key fingerprints and exit
-v show verbose messages
-load sessname Load settings from saved session
-ssh -telnet -rlogin -raw -serial
force use of a particular protocol
-P port connect to specified port
-l user connect with specified username
-batch disable all interactive prompts
The following options only apply to SSH connections:
-pw passw login with specified password
-D[listen-IP:]listen-port
Dynamic SOCKS-based port forwarding
-L[listen-IP:]listen-port:host:port
Forward local port to remote address
-R[listen-IP:]listen-port:host:port
Forward remote port to local address
-X -x enable / disable X11 forwarding
-A -a enable / disable agent forwarding
-t -T enable / disable pty allocation
-1 -2 force use of particular protocol version
-4 -6 force use of IPv4 or IPv6
-C enable compression
-i key private key file for authentication
-noagent disable use of Pageant
-agent enable use of Pageant
-m file read remote command(s) from file
-s remote command is an SSH subsystem (SSH-2 only)
-N don't start a shell/command (SSH-2 only)
-nc host:port
open tunnel in place of session (SSH-2 only)
-sercfg configuration-string (e.g. 19200,8,n,1,X)
Specify the serial configuration (serial only)
C:> for /F %i in ('plink -l username -pw password myserver echo $HOSTNAME') do SET VAR=%i
C:> echo %VAR%
gentoo
C:>
So your command might look like:
Code:
for /F %i in ('plink -l username -pw password myserverssh server1/tmp/abc.sh server1') do SET VAR=%i
This is a complicated command... The stuff in green happens on your windows machine, the stuff in red happens on myserver, and the stuff in blue happens on server1. If it doesn't work, try each level individually to see where it is breaking down.
-agent insead of -pw would be better if you can use an agent, of course.
