UBUNTU OPERATING SYSTEM





                 Ubuntu is a popular open-source operating system based on the Debian Linux distribution. It is developed and
                 maintained by Canonical Ltd. Ubuntu is known for its user-friendly interface, ease of use, and robust community
                 support.
































                 Working with Directories
                 In Ubuntu OS, as in any other operating system, files and directories serve fundamental roles in organising and
                 managing data within the file system.
                 Directories (Folders) in Ubuntu are containers that are used to organise and group related files and subdirectories.
                 In directories, files and subdirectories are arranged in the hierarchical structure (tree-like structure). In Ubuntu OS,
                 the root directory is denoted by /. This is the top-level directory in the file system hierarchy. Everything starts from
                 here.

                                                                    /




                    /bin  /boot  /dev  /etc  /home  /lib  /media /mnt  /opt  /proc  /sbin  /srv  /sys  /tmp  /usr  /var


                 Some commonly used directories in Ubuntu are:
                 •  /bin: It contains essential binaries (executable files) that are required for system operation. Common commands
                   like ls, cp, mv, etc., reside here.
                 •  /boot: It contains files necessary for booting the system, such as the kernel, bootloader configuration, and other
                   boot-related files.
                 •  /dev: It contains device files, which are used to interact with hardware devices.
                 •  /etc: It contains system-wide  configuration  files. Configuration  files for  various  services and  programs  are
                   typically stored here.
