  • What is a "variable"?
  • What are "environment variables" (or "system variables")?
  • How do I use comments in shell code?
  • What happens when I add multiple arguments to printf?
  • How do I display the size and panes in TMUX?
  • What are "fields" and "delimiters"?
  • How do I pass data and variables into my program?
  • What are "parameters"?
  • How do I get the first argument into my program?
