File System Support and Graphical User Interface

Linux supports a wide range of file systems, including Ext2, Ext3, Ext4, and NTFS, while Unix supports file systems such as jfs, hfs, and zfs. This difference in file system support allows Linux users to have greater flexibility and compatibility with various storage devices and file formats. On the other hand, Unix users may have specific requirements or preferences for the file systems they use, depending on their enterprise-level needs.

When it comes to the graphical user interface (GUI), Linux provides users with a variety of options, such as KDE and Gnome. These desktop environments offer visually appealing and user-friendly interfaces that make it easier for users to interact with the operating system and its applications. Unix, on the other hand, initially relied on a command-based interface and later developed the Common Desktop Environment (CDE), which is commonly shipped with Gnome. While Unix’s GUI has improved over time, Linux generally offers a more diverse and customizable experience for users.
