How could I use the value of return code
Hello,

I am woring on a script where I am getting strange situation.This script actually fetch the source code and tar that code and send to NAS location.This code resides in MKS tool...and we are fetching the source code on checkpoint label basis and script is working fine.First it synch the sandbox and after that it picks the checkpint value from release.txt for e.g R1_HOTFIX_220711 .The problem is when checkout happens it fetch the source code corresponding to checkpoint lable...so some files checkout and in some it gives that this files doesn't contain this tag or checkpoint label which is correct but my problem is it always retun code 128 if checkoint lable is correct or not..here the problem persist.I want to restrict my script that if checkpoint lable is not coorect it should not run next command.Here I want to tell you that if somefiles checkout then whose permisson change to read-write and except that all files are in readonly mode

Code:
#Release_File=/tmp/rohit/FetchCode.config
Release_File=/tmp/rohit/giga.config
Checkout_dir=/tmp/rohit/CheckoutRepo
Nas_Location=/tmp/rohit/Temp/
Release_Container=/tmp/rohit/PN_Release/
#Sandbox_dir=/tmp/rohit/ProjectSandbox
Sandbox_dir=/tmp/rohit/foo

MKS_Connection()
{
si connect --hostname=si.worln.com --port=7001 --user=1234LinuxAutomation --password=Hi
ReturnCode="$?"
echo $ReturnCode
if [[ "${ReturnCode}" -ne "0" ]];then
echo "mail"
else
echo "Connection to MKS Client is in progress"
fi
}

CodebaseFetch()
{
while read line
do
Repo_Path=`echo $line|cut -d ":" -f1`
Release_Name=`echo $line|cut -d ":" -f2`
Product_Name=`echo $line|cut -d ":" -f3`
CMD=$(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}" == "${Release_Name}" ]];then
si resync --sandbox="${Sandbox_dir}"/$Release_Name/$Release_Name.pj -Y --populate -f --restoreTimestamp --overwriteUnchanged --batch -R
sleep 50;
si co -R -f -l --nolock -r "${i}" --sandbox="${Sandbox_dir}"/$Release_Name/$Release_Name.pj -Y --batch --forceconfirm=yes
ReturnCode="$?"
echo $ReturnCode
if [[ "${ReturnCode}" -eq "128" ]];then
#find "${Sandbox_dir}/"${Release_Name}/ -perm 444 -type f -exec rm {} \;
tar -zcvf ESCROW-SOURCE_${Release_Name}.tar.gz ${Release_Name}
mv "${Sandbox_dir}"/ESCROW-SOURCE_${Release_Name}.tar.gz "${Nas_Location}"
else
echo "The value in ${Release_Name} is not correct"
fi
else
si dropsandbox --delete=none -Y "${Sandbox_dir}"/$Release_Name/$Release_Name.pj
mkdir "${Sandbox_dir}"/"${Release_Name}"
si createsandbox --noshared --recurse --nosparse --populate -Y --batch --cwd=${Sandbox_dir}/"${Release_Name}"/ --project=D:/"${Repo_Path}".pj
sleep 50;
si co -R -f -l --nolock -r "${i}" --sandbox="${Sandbox_dir}"/$Release_Name/$Release_Name.pj -Y --batch --forceconfirm=yes
ReturnCode="$?"
echo $ReturnCode
if [[ "${ReturnCode}" -eq "128" ]];then

tar -zcvf ESCROW-SOURCE_${Release_Name}.tar.gz ${Release_Name}
mv "${Sandbox_dir}"/ESCROW-SOURCE_${Release_Name}.tar.gz "${Nas_Location}"
else
echo "The value in ${Release_Name} is not correct"
fi

done < "${Release_File}";
