Jenkins pass a shell script variable to a down stream job - jenkins

Question

I'm new to Jenkins.
I have a job with an "Execute Shell" Build trigger, and in that shell script i initiate some variables with values i take from some source.
I need to pass these values to a downstream job.
The values i want to pass are $IMG_NAME and $IMG_PATH from this shell script:
#!/bin/bash -x
whoami
echo "BASE_PATH: $BASE_PATH"
declare -A BRANCHES
for i in $(echo $BRANCHES_LIST | tr ',' '\n'); do BRANCHES[$i]= ; done
echo 'user' | sudo -S umount -rf /mnt/tlv-s-comp-prod/drops/
echo 'user' | sudo -S mount.nfs -o nolock,nfsvers=3 tlv-s-comp-prod:/export/drops /mnt/tlv-s-comp-prod/drops
ls /mnt/tlv-s-comp-prod/drops/
echo "cleanup workspace"
rm ${WORKSPACE}/*.txt &> /dev/null
i="0"
while [ $i -lt 6 ]
do
if [[ ${BASE_PATH} == *"Baseline"* ]]; then
unset BRANCHES[#]
declare -A BRANCHES
BRANCHES[Baseline]=
fi
for BRANCH in "${!BRANCHES[#]}"; do
echo "BRANCH: $BRANCH"
if [ $BRANCH == "Baseline" ]; then BRANCH=; fi
img_dir=$(ls -td -- ${BASE_PATH}/${BRANCH}/*/ | head -n 1)
echo "img_dir: $img_dir"
IMG_PATH=$(ls $img_dir*.rpm)
echo "IMG_PATH: $IMG_PATH"
cd $img_dir
IMG_NAME=$(ls *.rpm) > env.properties
if [ ! -z "$IMG_NAME" ]; then
if [ $(( $(date +%s) - $(stat -c %Z $IMG_PATH) )) -lt 10000800 ]; then
echo "IMG_NAME: ${IMG_NAME}"
#BRANCHES[$BRANCH]=$IMG_PATH
#echo "REG_OSA_SOFTSYNC_BUILD_IMG_FULL_PATH=${BRANCHES[$BRANCH]}" >> ${WORKSPACE}/$BRANCH.txt
echo "BRANCH_NAME=$BRANCH" >> ${WORKSPACE}/${BRANCH}_branch.txt
echo "REG_OSA_SOFTSYNC_BUILD_NAME=$BRANCH-$IMG_NAME" >> ${WORKSPACE}/${BRANCH}_branch.txt
else
echo "$IMG_NAME is out dated"
fi
else
echo "IMG_NAME is empty"
fi
BRANCH_NAME=""
done
$TEMP=$BRANCH_NAME
echo "TEMP: $TEMP"
if [ $(ls ${WORKSPACE}/*_branch.txt | wc -l) == $(echo ${#BRANCHES[#]}) ]; then break; fi
#for i in $(ls *_branch.txt); do i=$(echo $i | awk -F '_branch.txt' '{print $1}'); if [ $(echo ${!BRANCHES[#]} | grep $i | wc -l) == 0 ]; then state=1 break; fi done
i=$[$i+1]
sleep 1800
done
This is the "Trigger parameterized build on other projects" configuration:
