Linxu file types and extensions

1) in Windows, the file type is distinguished by the extension name.

2) There is no relationship between the file extension and the file type in Linux.

3) in order to easily differentiate and be compatible with the user's habit of using Windows, we also use extensions to differentiate between file types.

In a Linux system, everything can be said to be files.

File types include ordinary files, directories, character device files, block device files, symbolic link files, etc.

B Block (buffered) special
