What are the functions of dir and vdir in Linux?

In Linux, the commands ‘dir’ and ‘vdir’ are used to display files and subdirectories in a directory.

The dir command is used to display a concise list of files and subdirectories in a directory. It shows the name of each file and subdirectory without providing additional details. By default, it sorts the list alphabetically by file name.

The vdir command is an enhanced version of the dir command, providing more detailed information about files and subdirectories. It displays detailed information such as file permissions, owner, size, modification date and time, and sorts them by default.

These two commands can assist users in quickly viewing directory structures and file information, making it easier to manage files and directories.
