Thanks for your quick reply.
I can able to ssh to other servers and able run the command. I'm getting emails from each server. To aviod this, I'm trying to append file using ssh using following command
ssh
user@some.domain "cat remote-source-file-name" >> local-target-file-name
since I have to add this command to the script for several servers and need to remove the file from all servers, the script will be too long.
if I can do it in oppisite direction using following command
cat local-source-file-name | ssh
user@some.domain "cat >> remote-target-file-name"
i can send result file from all servers and append to the file where (server A) the intial command runs. from there I can send an email with result file. But for this, Do I need to copy RSA keys from all servers to server A. Because when I run the above command, it asking me for the password. But I can ssh from server A to all other servers without the password. Any one have idea. Thanks.

service(8) System Manager's Manual service(8)
NAME
service - run a System V init script
SYNOPSIS
service SCRIPT COMMAND [OPTIONS]
service --status-all
service --help | -h | --version
DESCRIPTION
service runs a System V init script in as predictable environment as possible, removing most environment variables and with current working
directory set to /.
The SCRIPT parameter specifies a System V init script, located in /etc/init.d/SCRIPT. The supported values of COMMAND depend on the
invoked script, service passes COMMAND and OPTIONS it to the init script unmodified. All scripts should support at least the start and
stop commands. As a special case, if COMMAND is --full-restart, the script is run twice, first with the stop command, then with the start
command.
service --status-all runs all init scripts, in alphabetical order, with the status command.
If the init script file does not exist, the script tries to use legacy actions. If there is no suitable legacy action found and COMMAND is
one of actions specified in LSB Core Specification, input is redirected to the systemctl. Otherwise the command fails with return code 2.
FILES
/etc/init.d
The directory containing System V init scripts.
ENVIRONMENT
LANG, TERM
The only environment variables passed to the init scripts.
