In one virtual terminal window (see step 1) log in to a LINUX computer at tuxworld. usask. ca using the ssh command. In subsequent questions, we will refer to this virtual terminal window as the remote virtual terminal. In this question, you will use the tree command to get an idea of all the files that are present in your LINUX home directory. Issue the command "tree /studentsid" in your remote virtual terminal window (the one from step 12 running ssh ), where nsid is your NSID. That is, the command must be given on the tuxworld system. The command tells tree to output the entire file system subtree tree rooted at your LINUX home directory on the Department's file server. Take a screenshot of your remote virtual terminal and send it to the lab instructor via Direct Message on Discord. You are welcome to read the "man pages" for tree for other options that can customize the command's operation, and then try them out. 3. (1 mark) Use the id or groups command to show what groups you are in. Use the "ls l" command to show the group ownership of the files. 4. (2 marks) Make sure the above tasks are complete and have been shown to the lab instructor before moving on to this question. Go to your home directory. Demonstrate to the lab instructor that subdirectories demo1, demo2, and demo3 exist. Then, using an appropriate combination of the rm,rmdir and/or " rmr " commands, remove those subdirectories and their content. Finally, give evidence that the subdirectories and their content have been deleted
