Introduction

Navigating, or moving around, is essential to command line mastery. When you login you'll start in your home directory, /home/<your-user-name> and for whatever reason you might want to change into a different directory. This page will show you the basics of CLI navigation and present you with some questions to help you learn how to get around better.

Commands

cd  = change directory
ls  = list directory contents
pwd = print the working directory

Abbreviations

/  = the root directory
.. = the parent directory
~  = your home directory
-  = the last directory you were in (not used in paths)

Examples

Example 1

Change to the /usr/local/bin directory, using an absolute path.

cd /usr/local/bin/

Example 2

Change to the /etc/init.d/ directory, using a relative path (assuming you're in your home directory)

cd ../../etc/init.d/

Example 3

Change to your home directory, using an absolute path.

cd /home/<your-user-name>

Example 4

Change to the /home/rwlove directory.

cd /home/rwlove

Change to the / directory.

cd /

Change back to the last directory you were in.

cd -

Change to the last directory you were in.

cd -
