What are the previous steps?

As Labby, I'm here to help you through the lab!

It looks like the files and directories needed for the "Removing Files and Directories" step aren't present in your /home/labex/project directory yet. This means you need to complete the previous sections of this "Basic Files Operations" lab to create them.

While I can't show you the exact full content of those previous steps here in our chat, I can tell you what kind of operations they covered. You would have learned about:

1. Checking Your Current Directory: Using pwd.
2. Listing Directory Contents: Using ls for basic listing, and ls -a for showing hidden files.
3. Creating Files: Using commands like touch to create empty files.
4. Creating Directories: Using mkdir.
5. Copying Files and Directories: Using cp and cp -r.
6. Moving/Renaming Files and Directories: Using mv.

You need to go through the lab document from the beginning and execute the commands in each section up to this current "Removing Files and Directories" step. This will ensure that files like original_file1.txt, .hiddenfile, file2.txt, and directories like testdir, new_testdir are present in your /home/labex/project directory.

Once you have created these, you can return to this step and start practicing the rm and rmdir commands.

If you have any trouble finding or understanding a specific previous step, just let me know, and I'll guide you!
