sed删除与输入数据匹配的行的命令有什么问题？

输入数据.txt

123,
1234,
1453,

数据删除.txt

1234,hellofirstline
123,hellosecondline
14676,hellothirdline
1453,hellofourthline

Datatodelete.txt 中的预期输出

14676,hellothirdline

脚本：

echo "the script starts now"
while read EachLine
do
  echo $EachLine
  sed "/$EachLine/d" < /home/Datatodelete.txt >/home/dummy
done < /home/InputData.txt
