Was the project written in a compiled programming language?

Are the commands mentioned in the subject implemented from scratch, without calling any external binaries?

The use of execution commands (such as exec, system, os/exec, or similar functions) to call external binaries or utilities is strictly forbidden, as the project requires implementing all functionality from scratch without relying on external programs.

Can you confirm that the displayed message of the project is exactly the same as the computer terminal?

Try to run the command "pwd".

Can you confirm that the interpreter displayed the current path?

Try to open the project and create a parent folder with two children folders using the command "mkdir". Then enter the parent folder and do "pwd".

Can you confirm that the interpreter displayed the current path?

Try to enter a directory of your choice by using the command "cd dir/of/your/choice".

Can you confirm that the interpreter took you to the correct path? Use "pwd" to confirm.

Create a document inside the new_folder1 called new_doc.txt with some random text inside. Try to run the command "cp new_doc.txt ../folder2" to copy the document to the folder new_folder2.

Can you confirm that the document new_doc.txt is inside the new_folder2?
