🧰 Basic Syntax

cd [OPTION] [DIRECTORY]

• DIRECTORY: The path to the directory you want to move into.
• OPTION: Optional flags like -L or -P for symbolic link behavior.

🔄 Common Use Cases

1. Go to the Home Directory

cd
cd ~

2. Move to a Specific Directory

cd /var/log

3. Use a Relative Path

cd Documents/Projects

4. Go Up One Level

cd ..

5. Go Up Multiple Levels

cd ../../

6. Return to the Previous Directory

cd -

7. Handle Spaces in Directory Names

cd "My Documents"
cd My\ Documents

8. Use Absolute vs. Relative Paths

• Relative:

  cd Documents

⚙️ Options
