How to display and move between files in Terminal Install Python 3 as a part of the Command Line Developer Tools. When you first launch Terminal, you're starting in the current working directory of /Users/ myusername/ (also known as your User folder). You can then get to your Utilities folder by typing "./Utilities/" rather than "/Applications/Utilities". This tutorial references a shell application called bash, which is the default on OS X and ubiquitous on unix-based platforms. For instance, if you go to the "/Applications/" folder in Terminal, that's your current working directory ( cwd). Relative paths are defined based on where you've already navigated to, and represented by "./". So if you wanted to make a path to your Applications folder, you would write "/Applications/". In order to run Blender you will have to specify that path to the Blender executable inside this folder, to get all output printed to the terminal. These files are actually folders that appear as files in Finder. An absolute path starts at the root level of your hard drive, and is displayed as "/". These files are actually folders that appear as files in Finder. Paths take two forms: absolute paths and relative paths. Paths look similar in some ways to website sub-directories, and follow the structure of your folders. To do so, you build something called a path.
You can use Terminal to get direct access to your files without using the Finder. When writing commands and paths in Terminal, almost everything is case sensitive: This means that you need to remember to properly capitalize "Dock" when referring to the Dock, or OS X won't understand your command. Unless you're executing a command that requires the display of text in Terminal, you won't have any indicator that what you've done has been successful you'll just get a new line with your user name on it once the command is finished processing.
