  • Why terminals exist
  • Linux is a natural multi-user system
  • Types of things you can do in a terminal
  • Look in home directory and subdirectories in Nemo and terminal (ls, ls -l, ls -l -h, cd, pwd)
  • File not found, permission denied error exampls
  • Create some text files in Xed, view them with cat
  • Case sensitivity examples
  • Download example files using firefox
  • View a long text file in Xed, cat, less
  • Plain text files vs doc files; plain text vs xls; file command
  • Different image types, can't view in terminal, can check with file command
  • Extensions mostly don't matter in linux
  • Linux filesystem structure: one root, common directories
