Terminal พื้นฐานสำหรับใช้ Claude Codeterminal basics for Claude Code

This is not a full command line course. You only need enough Terminal to start Claude Code from the right folder.

The rule is simple: Claude Code works from the folder where you run claude. If you run it from the wrong folder, Claude sees the wrong context.

For a quick demo, open Terminal 101: learn to navigate. It shows Terminal and a file explorer side by side: type commands on the left and watch the folders change on the right; click a folder on the right and it shows the command that click was hiding.

the three questions

Use Terminal to answer three questions:

1. Where am I?
2. What is in here?
3. How do I move into the right folder?

Those map to three commands.

where am I: pwd

pwd

pwd prints the current folder. It may look like:

/Users/yourname/Desktop

You do not need to memorize the whole path. Just check the ending and make sure it matches where you think you are.

what is in here: ls

ls

ls lists the files and folders in the current folder.

On Windows PowerShell, ls also works. You may also see people use dir.

move folders: cd

Go into a folder:

cd folder-name

Go back one level:

cd ..

Go to Desktop on Mac:

cd ~/Desktop

If a folder name is long, type the first few letters and press Tab. Terminal can autocomplete the rest.

open the course workspace

After downloading and unzipping the starter workspace, put it somewhere easy to find, such as Desktop.

Then:

cd ~/Desktop
ls
cd claude-code-zero-to-hero-workspace
pwd
ls

The exact folder name may differ. The important part is that pwd ends with the workspace folder and ls shows the course files.

start Claude from the right folder

Only after you are inside the workspace, run:

claude

Then ask:

What is in this workspace, and what is this class likely using it for?

If Claude can explain the workspace, you opened it from the right folder.

quick recap

• pwd = where am I?
• ls = what is in here?
• cd folder-name = go into a folder
• cd .. = go back one level
• clear = clean the screen; it does not delete files
• run claude only after you are in the right workspace folder
