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-ARGV0(1) BSD General Commands Manual SSH-ARGV0(1)
NAME
ssh-argv0 -- replaces the old ssh command-name as hostname handling
SYNOPSIS
hostname | user@hostname [-l login_name] [command]
hostname | user@hostname [-afgknqstvxACNTX1246] [-b bind_address] [-c cipher_spec] [-e escape_char] [-i identity_file] [-l login_name]
[-m mac_spec] [-o option] [-p port] [-F configfile] [-L port:host:hostport] [-R port:host:hostport] [-D port] [command]
