${left_dir}

sed -i 's/*deleting/${left_dir}/g' ${list_file}

## 另一种方式就是 只查看 文件名称的区别 ，而不关注内容是否有区别

[root@pz_ne-oltp-etl-vm1 compare]# find 20200113 -printf "%P\n" | sort > file1
[root@pz_ne-oltp-etl-vm1 compare]# find 20200114 -printf "%P\n" | sort > file2
[root@pz_ne-oltp-etl-vm1 compare]# diff file1 file2
