Question Error with korn shell - arrays
Hi All

I have a FTP script which FTPs few files into an user folder. I intend to keep track of the folder size before FTP and after FTP and print that once the FTP script is run (a kind of comparison, "Before FTP, "After FTP").

I decided to use kron shells to accomplish this.
Code:
#! /bin/ksh

analyse_folders_pre() {

 # List of directories to check.
 dirNames[0]='bin'
 dirPath[0]='/home/user1/bin'
 dirNoFilesPre[0]=$(ls  ${dirPath[0]} | wc -l | awk '{print $1}')

 idx=0
 while [ $idx -ne 1 ]
 do
    tempSize=0
    dirFileSizePre[$idx]=0
    dirSize=0

    for i in $(ls ${dirPath[0]})
    do
      tempSize=$( ls -l $i | awk '{print $5}')
      ((dirSize=dirSize+tempSize))
    done
    dirFileSizePre[$idx]=$dirSize
    ((idx = idx+1))
 done

} ### End of analyse_pack_rel_pre

 ### Main Script Starts here ###
 # List of directories to check.
 dirNames[0]='bin'
 export dirNames

 dirPath[0]=''
 export dirPath

 dirNoFilesPre[0]=0
 export  dirNoFilesPre

 dirNoFilesPost[0]=0
 export  dirNoFilesPost

 analyse_folders_pre 

 ### Script to FTP
 ftp_files

 analyse_folders_post

 i=0
 while [ $i -ne 1 ]
 do
  echo ${dirNoFilesPre[$i]}
  echo ${dirFileSizePre[$i]}

  echo ${dirNoFilesPost[$i]}
  echo ${dirFileSizePost[$i]}
  ((i=i+1))
 done

But, I am getting the following error.
syntax error at line 8: `dirNoFilesPre[0]=$' unexpected

What might be wrong? Is there any better way to do it?

DESCRIPTION

       Use the ftprestart command to restart an FTP Server previously shut down by means of ftpshut(1M). The ftprestart command reads the shutdown

OPTIONS

       The ftprestart command supports the following options:

       -V	Display program copyright and version information, then terminate.

EXAMPLES

       Example 1: Sample Output from ftprestart

       The following example shows sample output from the ftprestart command:

       example% ftprestart
       ftprestart: /export/home/ftp/etc/ftpd/shutdown.msg removed.
       ftprestart: /export/home/virtual1/etc/ftpd/shutdown.msg removed.
       ftprestart: /etc/ftpd/shutdown.msg removed.

EXIT STATUS

       The following exit values are returned:

       0	Successful completion.

       >0	An error occurred.
