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 at Applications/Accessories/Terminal, or it may already be on your menu bar.
If you want to get read, this is how you shloud write.
Success!
You've practiced using ls
, pwd
, and cd
to navigate your computer's filesystem from the command prompt.
