If you run an ssh command remotely the stdout from the command is returned to your local terminal. You can capture it there and send to a local file. So, say you want the output of the date command from multiple servers put in a file and then emailed. You could just:
Code:
#!/bin/bash
hosts=( host1 host2 host3 )
for ((i=0;i<${#hosts[@]};i++)); do
ssh me@${hosts[$i]} "date" >> outputfile &
done
wait
mail -s "Results" me@domain.com < outputfile
if it's a script that has to run they you could have it in a shared location and run it
If there's something in the script that varies by server you're just going to have to work that out. Either have a different script in each location or, if you need more automation, have it accept command line input for the difference and pass it with the script:
Code:
#!/bin/bash
hosts=( host1 host2 host3 )
var=( var1 var2 var3 )
for ((i=0;i<${#hosts[@]};i++)); do
ssh me@${hosts[$i]} "/path/to/script.sh ${var[$i]}" >> outputfile &
done
wait
mail -s "Results" me@domain.com < outputfile

ypset
ypset(8) System Manager's Manual ypset(8)NAME
ypset - bind ypbind to a particular NIS server
SYNOPSYS
ypset [ -d domain ] [ -h hostname ] server
DESCRIPTION
In order to run ypset, ypbind must be initiated with the -ypset or -ypsetme options. See ypbind(8). ypset tells ypbind to get NIS ser-
vices for the specified domain from the ypserv(8) process running on server.
In cases where several hosts on the local net are supplying NIS services, it is possible for ypbind to rebind to another host even while
you attempt to find out if the ypset operation succeeded. For example, you can type:
example% ypset host1
example% ypwhich
host2
which can be confusing. This is a function of the NIS subsystem's attempt to know always a running NIS server, and occurs when host1 does
not respond to ypbind because it is not running ypserv (or is overloaded), and host2, running ypserv, gets the binding.
Server indicates the NIS server to bind to, and must be specified as a name or an IP address. This will work only if the node has a cur-
rent valid binding for the domain in question, and ypbind has been set to allow use of ypset. In most cases, server should be specified
as an IP address.
OPTIONS -d domain
Specify a domain other than the default domain as returned by domainname(1).
-h hostname
Set the NIS binding on host hostname
instead of the local machine.
