How to use cd -?

To use the cd - command in Bash, follow these steps:

Navigate to a Directory: Start by changing to a directory. For example:
```
cd /home/user/documents
```
Change to Another Directory: Move to a different directory:
```
cd /home/user/downloads
```
Return to the Previous Directory: Now, to go back to the directory you were just in (in this case, /home/user/documents), simply run:
```
cd -
```

What Happens:

When you execute cd -, Bash will switch you back to the last directory you were in and display its path.

Example in Action:

cd /home/user/documents   # Current directory: /home/user/documents
cd /home/user/downloads    # Current directory: /home/user/downloads
cd -                       # Returns to: /home/user/documents

This command is particularly useful for quickly toggling between two directories. If you have more questions or need further examples, feel free to ask!
