Validation in shell script.
Code:
PICKUPDIR=/home/ready/
DROPDIR=/home/downloaded/
TODAY=$(date '+%d%m%y')
LOGFILE=xyz-$TODAY.log
###########
#FUNCTIONS#
###########
#function to perform file transfer to servercopy folder
opalO ()
{
cd $PICKUPDIR
for fileName in `ls -1 TES_ONE*`
do
cp $fileName $DROPDIR
done
} >> $LOGDIR/$LOGFILE
#############
#Main Script#
#############
echo "Start trnasfer to downloaded \c" >> $LOGDIR/$LOGFILE 
date >> $LOGDIR/$LOGFILE
opalO
wait
echo "Start file renaming: \c" >> $LOGDIR/$LOGFILE
date >> $LOGDIR/$LOGFILE
cd $PICKUPDIR
for FILE in `ls Tes_ONE*.*`
do
echo ${FILE} " : File Moved" >> $LOGDIR/$LOGFILE
mv ${FILE} ${FILE}.arch 
done
echo "End" >> $LOGDIR/$LOGFILE
exit 0

opalO function transfer the files from 'ready' to 'downloaded' folder.
I want to keep validation,if there is no files (TES_ONE*) in ready folder then an error message(No Files Availble) should go into the log file.
How can i place this validation in the above code? Please assist me.

Thanks in advance.

DESCRIPTION

       Rnmail  is  a friendly interface for mailing replies to news articles.  It will ask several questions, then allow you to enter your letter,
       and then mail it off.  If you type h and a carriage return at any point, Rnmail will tell you what it wants to know.

       The -h form is used when invoked from rn.  If your editor can edit multiple files, and you want the article to which you  are  replying	to
       show  up  as  an  alternate  file, define the environment variable MAILPOSTER as "Rnmail -h %h %A".  You can also modify the the MAILHEADER
       environment variable to change the header file that rn passes to Rnmail.

	       Default: message not saved

       ORGANIZATION
