There are three commands that we'll be using at a command prompt to navigate the filesystem on your computer:
ls
pwd
cd
ls
lists the contents of a directory.
pwd
gives the full directory path to your current directory.
cd
moves you into a new directory (it stands for "change directory").
Let's practice using these commands.
Open a command prompt:
You can find the Terminal application through Spotlight, or navigate to Applications/Utilities/Terminal.
Practice using ls
, pwd
, and cd
Type each of these commands and hit enter:
ls
This lists all the files in your home directory.
pwd
This displays the full directory path to your current directory, which is your home directory.
cd /
This will change you into the /
root directory.
ls
This lists the contents of the /
root directory.
cd Users
This will change you into the Users
subdirectory of the /
root directory.
ls
You should see a list of all the files in /Users
, including the directory for your username -- your home directory.
pwd
This displays the full directory path to your current directory, /Users
.
cd ..
..
means "parent directory", so this command moved you up to the parent directory. You were in /Users
, so now you are in /
, the root directory.
ls
This lists the contents of the root directory, confirming where you are.
- You can use Tab to auto-complete directory and file names. So from inside the root directory, if you type
cd U
and hit Tab, the command prompt will auto-complete the directory name as much as it can. - The command prompt maintains a command history. You can use the up arrow to cycle through old commands.
Success!
You've practiced using ls
, pwd
, and cd
to navigate your computer's filesystem from the command prompt.
