Korn script to access multiple host and collect data
Hi, I'm newbie in Korn scripting as well as in Unix. I need to have a script to do the following.
1) ssh multiple hosts
-In my case, login credentials are not an issue as all keys authorized by default. Example of host IP (24.35.14.6, 24.35.14.7, 24.35.14.8, 24.35.14.9, 24.35.14.10)
2) do df -Ph | grep LR in every host and copy this line into /tmp/vvv. The line should be something like this. "hostname" : "df -Ph output"
3) After those lines, then append with this below.
"hostname" : "number of the line in this hostname"
4) Total number of df -Ph lines in all hostnames must be added above all the lines. Means the amount of total should be in first line.
Is this possible to do? Please help. And please brief in short sentence for every line of command as it may help me to know what the command does. I'm learning the script but I must do this task urgently. Your help is very much appreciated.......

uudemon.cleanu
uudemon(4) Kernel Interfaces Manual uudemon(4)
NAME
uudemon.admin, uudemon.cleanu, uudemon.hour, uudemon.poll - Administrative shell scripts for polling remote systems, cleaning up spool
directories, reporting status to the system administrator, and routine invocations of the uuxqt and uusched daemons
SYNOPSIS
These shell scripts reside in the following directory:
/usr/lib/uucp
DESCRIPTION
All the scripts can be run from the command line or can be run automatically by the cron daemon. To automatically run the scripts, remove
the comment character (#) from the beginning of the relevant line in the /var/spool/cron/crontabs/uucp file.
This script reports status to the system administrator. It issues the uustat command to find out the status of uucp jobs. It mails the
results to the uucp login ID. The script may be modified to send mail to any login ID such as the uucp administrative login ID (uucpa) or
root. This script cleans up the /var/spool/uucp and /var/spool/uucppublic directories by running the uucleanup command. The uucleanup com-
mand is run with the following parameters: -C7, -D7, X2, -o2, -W1. This script runs the uusched and uuxqt daemons in the background. This
script polls the systems listed in the /usr/lib/uucp/Poll file. The uudemon.poll script should be scheduled before the uudemon.hour
script. This allows uudemon.poll to create any command files before cron runs the uudemon.hour script.
FILES
Contains the uudemon.admin, uudemon.cleanu, uudemon.hour and uudemon.poll files. Contains the uucp file.
RELATED INFORMATION
Commands: cron(8), uucleanup(8), uusched(8), uuxqt(1)
