Files and File systems

First, let's review Intro Unix: Files and File Systems. The most important takeaways are:

• Understanding the tree-like structure of directories and files in the file system hierarchy
  • Absolute paths start with a slash ( / ), the root of the file system hierarchy
    
  • More at: Intro Unix: Files and File Systems: The file system hierarchy
    
• Knowing how to navigate the file system using the cd (change directory) command, Tab key completion, and relative path syntax:
  • use the dot ( . ) metacharacter for the current directory
  • use the dot-dot ( .. ) metacharacters for the parent directory

    • Intro Unix: Files and File Systems: Relative pathname syntax
• Selecting multiple files using pathname wildcards (a.k.a. "globbing")
  
  • asterisk ( * ) to match any length of characters
  • brackets ( [ ] ) match any character between the brackets, including hyphen ( - ) delimited character ranges such as [A-G]
  • braces ( {  } ) enclose a list of comma-separated strings to match (e.g. {dog,pony})

• A basic understanding of file attributes such as
  • file type (file, directory)
  • owner and group
    
  • permissions (read, write, execute) for the owner, group and everyone
