Condition to check whether configuration file is empty or not?

Code:

CMD=$(find "${Release_Container}" -iname "${Release_Name}"_Release.txt)
for i in `cat $CMD`
do
if [[ "${Product_Name}" == "MKS" ]];then
cd ${Sandbox_dir}
CMD1=$(find "${Sandbox_dir}"/* -iname "${Release_Name}" -type d | awk -F/ '{print $(NF)}' | head -1 )
if [[ "${CMD1}" == "${Release_Name}" ]];then
echo -e "################### CHECKOUT START #######################"
si resync --sandbox="${Sandbox_dir}"/$Release_Name/$Release_Name.pj -Y --populate -f --restoreTimestamp --overwriteUnchanged --batch -R
Count_File1=`find "${Sandbox_dir}/"${Release_Name}/ -perm 444 -type f | wc -l`
echo $Count_File1
sleep 5;
si co -R -f -l --nolock -r "${i}" --sandbox="${Sandbox_dir}"/$Release_Name/$Release_Name.pj -Y --batch --forceconfirm=yes
Count_File2=`find "${Sandbox_dir}/"${Release_Name}/ -perm 444 -type f | wc -l`
echo $Count_File2

The above is the code of my script which I am using to fetch the source code of checkpoint label from the MKS tool.Here I want some help to enhance my script ...like to add one more functionality
.IF you see at the top of the code CMD variable is looking for one of the configuration file ..._release.txt.and store that.after that in for loop it is reading the value in CMD varibale i.e. the value
which is in the configuration file and using that value to checkout the source code of that checkpoint lable so ultimately the value in configuration file is checkpoint label.I want your help here
to solve one of my problem i.e. I want if the configuration file is empty then it should display or print that file is blank..I want to know here any condition through which we can check that file is empty or not
like value of i is null

e.g.

Code:

if [ $i == "exist" ];then
checkout
else
file is empty
fi

Thanks

ppmtosixel(1)                                                 General Commands Manual                                                ppmtosixel(1)

NAME

       ppmtosixel - convert a portable pixmap into DEC sixel format

SYNOPSIS

       ppmtosixel [-raw] [-margin] [ppmfile]

DESCRIPTION

       Reads  a  portable  pixmap  as input.  Produces sixel commands (SIX) as output.  The output is formatted for color printing, e.g. for a DEC
       LJ250 color inkjet printer.

       If RGB values from the PPM file do not have maxval=100, the RGB values are rescaled.  A printer control header and a color assignment table
       begin the SIX file.  Image data is written in a compressed format by default.  A printer control footer ends the image file.

OPTIONS

       -raw   If  specified,  each  pixel  will  be explicitly described in the image file.  If -raw is not specified, output will default to com-
              pressed format in which identical adjacent pixels are replaced by "repeat pixel" commands.  A raw file is often an order  of  magni-
              tude larger than a compressed file and prints much slower.

       -margin
              If  -margin  is not specified, the image will be start at the left margin (of the window, paper, or whatever).  If -margin is speci-
              fied, a 1.5 inch left margin will offset the image.

PRINTING

       Generally, sixel files must reach the printer unfiltered.  Use the lpr -x option or cat filename > /dev/tty0?.

BUGS

       Upon rescaling, truncation of the least significant bits of RGB values may result in poor color conversion.  If the original PPM maxval was
       greater  than  100,  rescaling  also reduces the image depth.  While the actual RGB values from the ppm file are more or less retained, the
       color palette of the LJ250 may not match the colors on your screen.  This seems to be a printer limitation.
