Shell Programming and Scripting

Hi,
I had written an FTP script where in I loop through the directories and transfer the files from each and every directory of Windows to UNIX.

Now the problem is when

1. The connection is unable to be established I should return some error codes

2. When there is some system problem and the FTP doesnt happen also the error condition should be handled

I would like to know whether there are any ways to handle the error codes for all the above conditions.

I am currently modified the code to handle the problem like this in the following ways.

ftp -v -n -i ${IP_ADDRESS} <<==eoftp== >> $LOGFILE 2>&1
user ${USERID} ${PASSWORD}
lcd ${1}
cd ${2}
put ${3}
bye
==eoftp==
ret_val=$?
echo "After ftp: `date '+%d/%m/%Y %T'`" |tee -a $LOGFILE 2>&1
echo "ret_val..= ${ret_val}" |tee -a $LOGFILE 2>&1
if [[ ${ret_val} -ne 0 ]]
then
echo "FTP failed..." |tee -a $LOGFILE 2>&1
else
echo "FTP Successful..." | tee -a $LOGFILE 2>&1
fi


Do let me know the other codes to be checked for proper functionality with check for exceptions

Thanks
