Linux Tutorial Series – 23 – Recap

Here is the video version, if you prefer it:

Today let’s quickly review the things we learned:

• Shell is a program that runs commands
• Commands are programs you can run with options and arguments
• date and cal are used to display the time and the calendar (this is not so important)
• Use Up/Down arrows to search command history
• Use Left/Right arrows to navigate to individual characters of the current command
• Use the clear command to clear your Terminal window
• Exit a terminal command session with exit or press CTRL + D
• Directories are a way to organize files
• Files are resources that contain information
• We talked about what to expect in the directories of a typical Linux directory hierarchy
• Parent directory is one directory “above” your current directory
• Absolute path names start with the root folder and proceed onward
• Relative path names start from the folder you are currently in

Hope you refreshed your memory!
