>Granting Administrative Privileges:Assigning administrative privileges to a user to execute root commands without switching to root user. ( ie., testuser ) # usermod -G wheel testuserEdit '/etc/pam.d/su' file. the file looks like as below.# vi /etc/pam.d/su#%PAM-1.0 auth sufficient pam_rootok.so # Uncomment the following line to implicitly trust users in the "wheel" group. #auth sufficient pam_wheel.so trust use_uid # Uncomment the following line to require a user to be in the "wheel" group. #auth required pam_wheel.so use_uid auth substack system-auth auth include postlogin account sufficient pam_succeed_if.so uid = 0 use_uid quiet account include system-auth password include system-auth session include system-auth session include postlogin session optional pam_xauth.so

Un Comment the below lines from the file."auth sufficient pam_wheel.so trust use_uid" "auth required pam_wheel.so use_uid"The file will be looks like below.# vi /etc/pam.d/su#%PAM-1.0 auth sufficient pam_rootok.so # Uncomment the following line to implicitly trust users in the "wheel" group. auth sufficient pam_wheel.so trust use_uid # Uncomment the following line to require a user to be in the "wheel" group. auth required pam_wheel.so use_uid auth substack system-auth auth include postlogin account sufficient pam_succeed_if.so uid = 0 use_uid quiet account include system-auth password include system-auth session include system-auth session include postlogin session optional pam_xauth.so

> User aliases: Creating an alias for the root user and forwarding all root user emails another user. ( ie., testuser ) # vi /etc/aliasesuncomment the last line and enter the username as shown below.root: testuser

> Reloading aliases: # newaliases

> Testing:Try to login to root user from testuser. in general, it should ask for the password. but testuser having root privileges so that we can login without entering any password like a root user.$ su -l root #

What is Linux?

  Linux is the open source operating system. As an operating system, Linux is software that sits underneath all of the other software on a computer, receiving requests from those programs and relaying these requests to the computer’s hardware. Just like Windows XP, Windows 7, Windows 8, Windows 10 and Mac OS X, Linux is an operating system. An operating system manages the communication between your software and your hardware. Without the operating system (often called as “OS”), the software wouldn’t function. The OS is the combination of the following pieces: The Bootloader: This is the process that manages the boot process of your computer. The kernel: Actually the kernel is called "Linux". The kernel is the core of the system and manages the CPU, memory, and peripheral devices. The kernel is the “lowest” level of the OS. Daemons: These are background services (printing, network, sound, scheduling, etc) that either start up during boot process or after you log into the desktop. The Shell: The Linux command line, This is the shell that allows to control the computer via commands. Graphical Server: This is the process that displays the graphics. It is commonly referred to as the X server or just “X”. Desktop Environment: This is the Graphical Desktop Environment in other words Graphical User Interface (GUI). There are many desktop environments like GNOME, KDE, MATE, XFCE, Cinnamon, Unity etc. Each desktop environment includes built-in applications such as file managers, configuration tools, web browsers, games, etc. Applications: In every Desktop environment we cannot get all kinds of apps. Just like in Windows and Mac, In Linux we can get thousands of high-quality softwares can be easily found and installed. For example: Ubuntu Linux has the Ubuntu Software Center which allows you to quickly search among the thousands of apps and install them from one centralized location. (Example: below pic)
