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.

isympy

isympy(1)																 isympy(1)

NAME

       isympy - interactive shell for SymPy

SYNOPSIS

       isympy [-c | --console]
       isympy [ {-h | --help} | {-v | --version} ]

DESCRIPTION

       isympy  is  a  Python shell for SymPy. It is just a normal python shell (ipython shell if you have the ipython package installed) that exe-
       cutes the following commands so that you don't have to:

       >>> from __future__ import division
       >>> from sympy import *
       >>> x, y, z = symbols("xyz")
       >>> k, m, n = symbols("kmn", integer=True)

       So starting isympy is equivalent to starting python (or ipython) and executing the above commands by hand. It  is  intended  for  easy  and
       quick  experimentation  with  SymPy. For more complicated programs, it is recommended to write a script and import things explicitly (using
       the "from sympy import sin, log, Symbol, ..." idiom).

OPTIONS

       -c shell, --console=shell
	      Use the specified shell (python or ipython) as console backend instead of the default one (ipython if present or python otherwise).

	      Example: isympy -c python

FILES

       ${HOME}/.sympy-history
	      Saves the history of commands when using the python shell as backend.

BUGS

       The upstreams BTS can be found at <http://code.google.com/p/sympy/issues/list> Please report all bugs that you find  in	there,	this  will
       help improve the overall quality of SymPy.
