The principle of implementation is as follows

1. Monitor whether the MD5 value of the file is the same before and after. If it is different, an error will be reported when comparing md5sum.

two。 Use the tree command to output to the specified file, and use diff to compare whether the two generated contents are the same. If there are more or less files, you will be prompted.

Knowledge points:

Md5sum-c: the MD5 value can be compared before and after. If the comparison fails, it will prompt FAILED.

Tree-I: remove the tree structure and display it directly as a column
