• The command line is also known as a terminal; it’s a text based interface to your computer system. It works by typing commands and receiving feedback as text.
• You can have several command lines open and doin different tasks at the same time, while also jumping back into the GUI when you need to.
• You’re typically given a prompt and you mostly issue commands
• Find your terminal in yoru computer’s applciations, typically under utilities.
• The shell: each terminal has a shell - the part of the os that defines how the terminal will behave and look after executing commands; the most common shell is “Bash” - bourne again shell.

• PWD = Print Working Directory: Tells you your current location
• ls = List: lists what is in the current file
• CD = change directory
• Root directory: the very top of the structure; denoted by a single slash (/); has subdirectories
• Types of paths:
  1. Absolute: specify a location in relation to the root directory (begins with /)
  2. Relative: specify a location in relation to where you are in the system
• ~ tilde is a shortcut for home directory
• . (dot) is a reference to yoru current directory
• .. (dot dot) is a reference to the parent directory

More About Files

Source: https://ryanstutorials.net/linuxtutorial/aboutfiles.php

• Everything is a file: text file/directory/keyboard = all files.
• Examples of File extensions:
  1. file.exe
  2. file.txt
  3. file.png / .gif / .jpg
• Linux is extensionless - so it ignores the extension
• file [path] will tell you the type of file in Linux

Tips:

• Linux is case sensitive
• Must be careful with spaces in names as spaces on the command line separate items
• Quotes around an entire item will keep them together

• Escape characters like () will escape or nullify the special meaning of the next character.

• Hidden Files
• To make a file hidden, you just have a file or directory name start with a “.” ; do the reverse to make it unhidden.
• ls won’t show hidden files,
• use ls -a to show hidden files and directories
