Full Discussion: ksh scripting SSH to Compare File Sizes
Top Forums Shell Programming and Scripting ksh scripting SSH to Compare File Sizes Post 303025376 by Chubler_XL on Wednesday 31st of October 2018 07:01:40 PM

Another approach using ksh. I setup two arrays of the FILES to check and the HOSTS.

Then as and example, I print each file name and it's size on host numbers 0,1 and 2.

Code:
#!/bin/ksh

set -A FILES /root/directory1/files/file1.fil /root/directory2/files/file2.fil
set -A HOSTS user@server2 user@server3

i=0
while [[ $i -lt ${#HOSTS[@]} ]]
do
   set -A FS$i $(ssh ${HOSTS[i]} "stat -c%s ${FILES[@]}")
   ((i++))
done

i=0
while [[ $i -lt ${#FILES[@]} ]]
do
  echo ${FILES[i]} ${HOSTS[0]}=${FS0[i]} ${HOSTS[1]}=${FS1[i]} ${HOSTS[2]}=${FS2[i]}
  ((i++))
done

HOSTS.CONF(5)							    NUT Manual							     HOSTS.CONF(5)

NAME

       hosts.conf - Access control for Network UPS Tools CGI programs

DESCRIPTION

       The CGI programs (upsset.cgi(8), upsstats.cgi(8), upsimage.cgi(8)) use this file to determine if they are allowed to talk to a host. This
       keeps random visitors from using your web server to annoy others by creating outgoing connections.

DIRECTIVES

       MONITOR ups description
	   The ups element is in the form upsname[@hostname[:port]]. To allow connections to a UPS called "snoopy" on a system called "doghouse"
	   that runs upsd on port 7877, it would look like this:

	       MONITOR snoopy@doghouse:7877 "Joe Cool"

	   The description must be one element, so if it has spaces, then it must be wrapped with quotes as shown above. The default hostname is
	   "localhost".
