Using xapply efficiently?

Hi all,

Were currently using xapply to run multiple ssh instances that then calls
a script that returns the PID of a webserver process.

Currently we have like 30 xapply statements in a script call checkit which
checks various webserver processes on various unix/linux boxes.

My question is is there a more efficient way of handling these instances
then calling 30 xapply statments? Could this script be written with just
one xapply? Heres what one line of code looks like for one of these instance.

xapply 'ssh %1 ./fccserv1' ajaxdev1
xapply 'ssh %1 ./<script name>' <servername>

Add about 30 more lines with the script name and server name changing for each line.

Thanks!

ssh-copy-id

SSH-COPY-ID(1)						      General Commands Manual						    SSH-COPY-ID(1)

NAME

       ssh-copy-id - install your public key in a remote machine's authorized_keys

SYNOPSIS

       ssh-copy-id [-i [identity_file]] [user@]machine

DESCRIPTION

       ssh-copy-id is a script that uses ssh to log into a remote machine (presumably using a login password, so password authentication should be
       enabled, unless you've done some clever use of multiple identities)

       It also changes the permissions of the remote user's home, ~/.ssh, and ~/.ssh/authorized_keys to remove group writability (which would oth-
       erwise prevent you from logging in, if the remote sshd has StrictModes set in its configuration).

       If  the -i option is given then the identity file (defaults to ~/.ssh/id_rsa.pub) is used, regardless of whether there are any keys in your
       ssh-agent.  Otherwise, if this:

	     ssh-add -L

       provides any output, it uses that in preference to the identity file.

       If the -i option is used, or the ssh-add produced no output, then it uses the contents of the identity file.  Once it has one or more  fin-
       gerprints (by whatever means) it uses ssh to append them to ~/.ssh/authorized_keys on the remote machine (creating the file, and directory,
       if necessary)
