Linux Environment renaming files

When renaming a file in a Linux environment, if the renamed file name is the same as the file name that already exists under the current path, the renamed file overwrites the file content of the same name;

For example: New file Testfile1, content is mytest;

New file Testfile2, content is test;

After performing the MV Testfile1 testfile2 command, the current path has only one testfile2 file, the content is mytest;

Test the file with the same name to the processing mechanism should be noted;
