Vi editor in UNIX hwk HELP!!
i need help with this homework. PLEASE

Assignment:
Create a directory "preFinal" in your home directory. Create empty files "a", "b", "c", etc in directory preFinal in the amount that match the number of directories preFinal*

This the code i have within Vi editor. But it is not working all the way. After runing bash about 10 times the letters jump from i to a random number and not in abc order. PLEASE TELL me how to do this.
Code:
#!/bin/bash

dir="preFinal"

if [ -d $dir ]; then
       echo "dir exists, moving..."
       i=0
       for dir_bkp in `ls -lrt | grep "^d" | egrep "preFinal*" | awk '{print $NF}' | sort -nr`; do
               next=$(echo "$dir_bkp" | sed 's/^.*\.//')
               if [ $next == "preFinal" ]; then
                       next=-1
               fi
               next=`echo $next|sed 's/^0*//'`
               ((next++))
               next=$(printf "%03d" $next)
               #next="00$next"
               echo $next
               mv $dir_bkp $dir.$next
               ((i++))

SYNOPSIS

       cd ?dirName?

DESCRIPTION

       Change the current working directory to dirName, or to the home directory (as specified in the HOME environment variable) if dirName is not

EXAMPLES

       Change to the home directory of the user fred:
	      cd ~fred
