Display the current working directory. 2. Create a new directory called "test_dir" in the current working directory. 3. Change the current working directory to "test_dir". 4. Verify the current working directory has been changed. 5. Create a new file named "test_file.txt" in "test_dir". a. You must write the following contents to test_file.txt: This is a test file. 6. Verify that "test_file.txt" was created by listing the contents of "test_dir". 7. Display the file size and the last modification time of "test_file.txt". 8. Change the name of "test_file.txt" to "new_test_file.txt". 9. Verify the name change by listing the contents of "test_dir" again. 10. Finally, remove "new_test_file.txt" and "test_dir", verifying each deletion by listing the contents of the parent directory.
- Which of the following operations should only be allowed to be done when the CPU is in kernel mode? Group of answer choices 1) Read data from a file 2) Open a file for reading, writing, or both 3) Set the time-of-day clock 4) Read the time-of-day clock A programmer opened a file using the file descriptor fd.

- I Need Help on Choice #3, Thank you!! You should approach this assignment in several parts.
