Class 2 - The Coder’s Computer

Files

• Everything is a file in Linux (even directories)
• Linux is case-sensitive
• file [path] - obtain information about what type of file a file or directory is

Basic Commands

• pwd - Print Working Directory tells you what directory you’re currently in
• ls - lists the directories or files within your current directory
  • ls -a - shows all files in the directory, including hidden files
  • ls -l - shows the long list of files to include permissions and file type
  • ls Documents - Relative paths specify a location (file or directory) in relation to where we currently are in the system. They will not begin with a slash
  • ls /home/ryan/Documents - Absolute paths specify a location (file or directory) in relation to the root directory. You can identify them easily as they always begin with a forward slash ( / )
• cd [location] - Change Directory to…change the directory we want to be in
  • cd .. - Use two periods to go back to the directory directly above the current location.
  • Use x+1 periods to go back x directories
• mv [file name] [file name] - moves file from first location to second location. Second location can be a new location.
