Is Linux shell a CUI?
Strictly speaking, a "shell" is simply the interface between the user and the rest of the operating system. In that definition not all shells on Linux are command lines. However, most day-to-day usage of the term "shell" does refer to command line user interfaces. Finally, "Linux shell" is not a thing. Linux is an operating system, specifically a kernel, not a shell. Most Linux distributions use BASH, but I personally prefer ZSH.

What is sudo?
sudo is a Linux command used to execute programs as the root, or "super user." sudo is a shortening of "super user do." One uses sudo when they need to run a command or program as root, but do not wish to log out or switch their entire shell to root privileges (like they could do with the su command). The file sudoers defines per user or per group what commands can be run with sudo. This file is edited with the command visudoers

What is diffrance between Linux and unix?
Shell is a program which allows the user to access the computer system. Shell is an interface between the user and computer system. Kernel is the only way through which the programs (all programs including shell) can access the hardware. Its a layer between the appliation programs and hardware. It is the core of most of the operating systems and manages everything including the communication between the hardware and software. KERNEL is the core part of operating system. It contain modules like device modules and other modules etc. Kernel is written in C language. Basically kernel is mediator between hardware and Operating System. But SHELL is an interface between users and operating system. Both are mediator but work is totally different. Let we have an example of "eject" command in Linux operating system: User give a command to Shell through input device like keyboard and see that command on video Device like monitor, but in actual concept is user give a command to shell, then this shell transfer that command to kernel.when kernel have module of that command then it transfer to hardware like CDROM. After that hardware behave as the module in kernel and then kernel again transfer the output to Shell. And finally shell transfer that output to user. Hardware <---> Kernel <---> Shell <---> User
How do you obtain root permissions in Linux?
