Terminal Emulator

• It is called "emulator" as it emulates the legacy mechanical terminals.
• It is a program/application window that is loaded on the screen.
• Official apps: gnome-terminal, xfce4-terminal, konsole, xterm, uxterm, etc.
• Third party apps: alacritty, kitty, terminator, tilix, st, etc.
• You can install and use different terminal apps on the same OS.

Shell

• Program which interprets commands typed by the user and shows the result.
• Type echo $0 echo ${SHELL} in terminal to check your current shell.
• You can install and use different shell programs on the same OS.
• Type "builtin" and press tab in terminal to view builtin commands into the bash shell.
• Every shell has system-wide and user-specific configuration files which can be customized.
• Standard Shells: sh, bash.
• Custom Shells: zsh, fish, oil.
• A shell can be either login or non-login.
• Login shell is started when a user logs into the system.
• Non-login shell is started when a application/program launches a shell.
• A shell can be either interactive or non-interacrive.
• Interactive shell is where user interacts directly eg. typing commands in TTY or terminal.
• Non-interactive shell is where user interacts indirectly eg. a script containing commands.

Command Line Interface (CLI)

• Interface where you interact with computers using lines of text instead of using GUI.
• It is generally done using a TTY interface or via terminal app.
• Updating system using CLI: $ sudo apt-get update && sudo apt-get dist-upgrade
• Launch nemo file manager using CLI: $ nemo

Prompt

• The text that you see when you open terminal.
• By default it should show [username]@[hostname][directory][:][prompt sign]
• Username : The name of the current user logged in.
• Hostname : The name of the computer user logged into.
• Directory : The path the user is currently in. "~" is the home directory of the current user.
• Prompt Sign : It shows "$" for non-root user and "#" for root user.
• Example: galileo@physics:~$
• User "galileo" is current logged into machine "physics" and is currently inside "home" directory
• Example: antoine@chemistry:/home/Downloads$
• User "antoine" is current logged into machine "chemistry" and is currently inside "/home/Downloads" directory
• Example: root@linux:/usr/bin#
• User "root" is current logged into machine "linux" and is currently inside "/usr/bin." directory
• You can customize your prompt to add features such as date, time, git status, exit status, newline, custom prompt sign, etc.
