There are three types of files in Unix: Ordinary File: Files created by users to store programs and data. Directory: Files that provide the mapping between names of files and the physical files. Special File: Files used for the control of devices. The “ls -ls” command will display all files information in your current directory.
Since the UNIX system upgrade of 2020, new remote access to UNIX desktop service is supported by VDS service. It is a virtualized technology that can create a brand new UNIX desktop on the fly as you request, and the changes to the desktop will be erased after logout.
