Assumptions are never good, but you've given little to go on, so Im assuming:
1) Ksh or maybe bash
2) you'll start the remote 'jobs' with ssh
3) the list of remote hosts is in some file, maybe with the command to execute on that particular host
The job file contains the host names followed by the exact command you'd like to run on that host.
In a korn shell script, how can I run several processes in parallel at the same time?
For example, I have 3 processes say p1, p2, p3
if I call them as
p1.ksh
p2.ksh
p3.ksh

ssh-copy-id
SSH-COPY-ID(1) BSD General Commands Manual SSH-COPY-ID(1)NAME
ssh-copy-id -- copy public keys to a remote host
SYNOPSIS
ssh-copy-id [-lv] [-i keyfile] [-o option] [-p port] [user@]hostname
DESCRIPTION
The ssh-copy-id utility copies public keys to a remote host's ~/.ssh/authorized_keys file (creating the file and directory, if required).
The following options are available:
-i file
Copy the public key contained in file. This option can be specified multiple times and can be combined with the -l option. If a
private key is specified and a public key is found then the public key will be used.
-l Copy the keys currently held by ssh-agent(1). This is the default if the -i option was not specified.
-o ssh-option
Pass this option directly to ssh(1). This option can be specified multiple times.
-p port
Connect to the specified port on the remote host instead of the default.
-v Pass -v to ssh(1).
The remaining arguments are a list of remote hosts to connect to, each one optionally qualified by a user name.
EXIT STATUS
The ssh-copy-id utility exits 0 on success, and >0 if an error occurs.
EXAMPLES
To send a specific key to multiple hosts:
$ ssh-copy-id -i /path/to/keyfile.pub user@host1 user@host2 user@host3
HISTORY
The ssh-copy-id utility was written by Eitan Adler <eadler@FreeBSD.org> as a drop-in replacement for an existing utility included with
OpenSSH.
