my requirement is if "Date" matches with the list of dates present in "file.txt", then it should say sucess "Date has matched".
#!/bin/bash
Date="Jun212018"
for i in `cat /home/file.txt`
do
if [ $i == $VT ]
then
echo "Date has Matched"
fi
done
shell cron

Your script leaves VT undefined (unless it's set in the environment, but that leaves Date unused).
A simpler script:
#!/bin/sh
if grep -q -Fx 'Jun212018' /home/file.txt; then
echo 'Date has Matched'
fi
This prints the string if the date Jun212018 matches exactly on a single line in the file.
From comments below, it seem this is what you want to be doing:
#!/bin/sh
today=$( date +%b%d%Y )
if grep -q -Fx "$today" /home/file.txt; then
echo 'date has matched' >/home/otherfile
fi
