Creating multiple extensions

Shell Programming and Scripting

Friends

I want to automat sending a letter to different persons whose directories are named as 001, 002, 003, 004.

To push the same letter to all these directories, I need to name the letter as letter.001, letter.002 like that.

Is there any method whereby I get the extension of this letter as myletter.001, myletter.002 etc.

Please help and thanks in advance

#! /bin/bash

count=001
max_count=025
while [ $count -le $max_count ]
   do
   countt=$(printf "%.3d" "$count")
   echo $countt
#insert commands to do for every iteration here
   cp demo_letter letter."$countt"
#  mailx -s "Important Notice" person@xyz.com <<letter."$countt"
   count=$((count+1))
done

Thanks a lot.

The requirement is like this.
At regular intervals I need to send a letter to all my clients. They are identified with 001, 002, 003....... I would like to send a letter viz. myletter.doc to all of them. For automating I need to create an extension like myletter.doc.001, 002..... so that they can be pushed to respective directories.

thanks once again.
