Objective: Practice common UNIX commands for file and directory manipulation.

Instructions: Perform each task in your UNIX/Linux terminal. Verify each step's completion before moving to the next.

---

Task List:

1. Environment Setup:

   • Create a new directory named unix_lab in your home directory.

   • Change your current directory to unix_lab.

   • Confirm your current working directory.

2. File and Directory Creation:

   • Create three empty files: document1.txt, notes.md, and report.log.

   • Create two subdirectories within unix_lab: projects and backups.

   • List all files and directories (including detailed information) in unix_lab to verify their creation.

3. File Content Management:

   • Add the line "This is the content for document one." to document1.txt.

   • Append the line "This is the second line." to document1.txt.

   • Add "# My Daily Notes", "* Remember to buy groceries", and "* Schedule meeting with John" (each on a new line) to notes.md.

   • Display the complete content of document1.txt.

   • Show only the first line of notes.md.

   • Display the last two lines of notes.md.

4. File Manipulation (Copying, Moving, Renaming):

   • Copy document1.txt into the backups directory.

   • Verify document1.txt is present in backups.

   • Rename notes.md to daily_notes.md in the current directory.

   • Move report.log into the projects directory.

   • Verify report.log is now in projects.

5. Searching:

   • From within unix_lab, find all files with the .txt extension.

   • Search for the word "content" within document1.txt.

   • Search for the word "meeting" within daily_notes.md.

6. Archiving and Compression:

   • Navigate back to your home directory.

   • Create a tar archive of the entire unix_lab directory, naming it unix_lab_archive.tar.

   • Compress unix_lab_archive.tar using gzip.

   • Confirm that unix_lab_archive.tar.gz exists.

7. Cleanup:

   • Create a new directory named extracted_lab.

   • Move unix_lab_archive.tar.gz into extracted_lab.

   • Change into the extracted_lab directory.

   • Decompress unix_lab_archive.tar.gz.

   • Extract the contents of unix_lab_archive.tar.

   • Navigate back to your home directory.

   • Delete the original unix_lab directory and all its contents. (Exercise caution!)

   • Delete the unix_lab_archive.tar.gz file.

   • Delete the extracted_lab directory and all its contents.

   • Verify that unix_lab, unix_lab_archive.tar.gz, and extracted_lab are no longer present in your home directory.
