File systems, files, and file manipulation
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

- Absolute paths start with a slash ( / ), the root of 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
- More at:
- 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})
