So What I understand you need to run script around lot of servers parallel. Copy the scrip to all servers and put in cron etc .... if you feel the script changes all the time then use
1. scp to copy script to all servers .
2. set at job or cron using ssh once scp is done.


About the script which you asked ... looks like it is trying to get rid of .txt extensions from all file in $dir directory ...

done
filename=$dir/Network_Elements.out
Here is a easy way you can replicate ...
1. go to test server/tmp/where you cannot harm server
[very imp]
2. copy the lines in a file
3. make it executable
4. make/copy some .txt files from production server

Now you can see what happns

You should learn some bash scripting and sed . what I can see in script is script is basically checking some file and batch_rlogin might be script/alias which external to this script.

Contact me if you need more help

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)

       Files: /usr/lib/uucp delim off
