How do I navigate between directories?

That's a very important question for working in Linux!

To navigate between directories, you use the cd command, which stands for "change directory".

Here are some common ways to use cd:

Go to a specific directory (absolute path):
If you know the full path to a directory, you can go there directly.
```
cd /home/labex/project
```
This command would take you directly to the /home/labex/project directory, regardless of where you currently are.
Go to a specific directory (relative path):
You can navigate using paths relative to your current working directory.
- If you are in /home/labex and you want to go into the project directory (which is inside labex):
```
cd project
```
- If you are in /home/labex/project and you want to go into a subdirectory called my_files:
```
cd my_files
```
Go up one level (parent directory):
The .. (double-dot) represents the parent directory.
- If you are in /home/labex/project and want to go back to /home/labex:
```
cd ..
```
Go back to your home directory:
There are a few ways to quickly return to your home directory:
- Using ~ (tilde):
```
cd ~
```
- Simply typing cd without any arguments:
```
cd
```
Both of these commands will take you to your home directory, which for you is /home/labex.
Go to the previous directory you were in:
The - (hyphen) character can take you back to your last working directory.
```
cd -
```
This is very handy for toggling between two frequently used directories.

Before you cd:
It's often helpful to use ls first to see the contents of your current directory and identify the directories you might want to enter.

Example workflow:

pwd             # Let's say you are in /home/labex/project
ls              # See what's inside /home/labex/project
cd ..           # Go up to /home/labex
pwd             # Now you are in /home/labex
cd project      # Go back down into project
pwd             # Now you are in /home/labex/project
