Shell programming Exercise-Copy the specified file (keep the directory structure of the file)

1. Purpose
Copy all files larger than 1M (customizable) in the/root directory to the/tmp/bakdir (customizable) directory, and you need to keep the directory structure.
For example, the/root/reed.file file size is 12M and will be copied to the/tmp/bakdir/root/path location.
2. Difficulty
It needs to be copied along with the path where the file resides.
3. Knowledge points
3.1 operation of files and directories (dirname command)
3.2 File Lookup operation (Find command)
3.3SHELL Programming Basics
4. Thinking and concrete realization
4.1 Ideas
1) Find the specified file first;
2) According to the found file, output its path;
3) Create the path and copy the file.
4.2 Effects
Original catalog file:
