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
