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

rplay.hosts

RPLAY.HOSTS(5)							File Formats Manual						    RPLAY.HOSTS(5)

NAME

       rplay.hosts - rplay host authentication database

SYNOPSIS

       /usr/local/etc/rplay.hosts

DESCRIPTION

       The  rplay.hosts  file contains a list of hosts and access permissions which rplayd uses to validate incoming connections.  Each line is of
       the form:

	      hostname[:permission]

       where

       hostname       is the name of a remote host or a host's IP address.  Wildcards can be used within IP addresses  to  match  multiple  hosts.
		      The wildcard character is "*".

       permission     is an optional field containing any combination of the following characters:

		      r  the host can read sounds.

		      w  the host can write sounds.

		      x  the host can play, stop, pause, and continue sounds.  This is normally called execute permission.

		      m  the host can monitor the audio stream written by rplayd to the audio device.

       "rx" permissions are used when no permissions are specified.

EXAMPLE

       #
       # All hosts have read access:
       #
       *:r

       #
       # Trusted hosts:
       #
       nice-guy.sdsu.edu:rwx
       friend.sdsu.edu:rwx
       amigo.sdsu.edu:rwx
       130.191.224.224:rwx

       #
       # Hosts which can read and execute:
       #
       foo.bar.com:rx
       130.190.*:rx
       146.244.234.*:rx
       using.default.perms.edu

       #
       # Hosts which can monitor the audio stream
       #
       nsa.sdsu.edu:m

FILES

       /usr/local/etc/rplay.hosts

SEE ALSO

       rplayd(1)

BUGS

       The permissions for an "*" entry apply to all matching hosts.  The order of this file does not matter.  Specific hosts can have access dis-
       abled with entries like:

       bad.guy.edu:

       however, any matching "*" entries will still apply.
