In the last few examples, you moved between the /var and /usr/bin directories by specifying either relative or absolute paths. Switching back and forth between two directories is something you’ll do more often than you’d think. This has a nice shortcut command. Whenever you change to a new working directory, your shell stores the previous directory.
To switch back to the previous directory, use cd -. This command retrieves the value of the previous directory and uses it to change the directory.
Try this exercise out. First, go to your home directory. Then, navigate to the /var directory. Use cd - to switch back and forth between the two:
| | $ cd |
| | $ cd /var |
| | $ cd - |
| | /home/brian |
| | $ cd - |
