6. File copy, move, and removal. Use one command to finish each step. You should not use "cd" command at all. Under your home directory, create a new text file using your campus email id as the file name. Create a copy of the file in the same directory using any name you like. Create a subdirectory "backup". Move the original file to "backup" and rename it using your first name. Create a copy of the "backup" directory (and all file in it); name it "backup2". Delete "backup". Rename "backup2" to "backup3". List the files in the new directory. Take a screenshot (#3-5) that clearly shows the command you use and the result. 7. Link a) Go to your "Documents" directory: b) Create a file "file1" with the text "hello" in it; c) Create a hard link named "file2" linked to "file1"; d) Create a soft link named "soft1" linked to "file1"; create another soft link named "soft2" linked to "file2". e) View information of the 4 files (what command should you use to produce some output same to the figure below) - what's the difference of these 4 files? 935008 -rw-r--r-- 2 root root 6 2011-09-08 00:52 filel 935008 -rw-roor. 2 root root 6 2011-09-08 00:52 file2 936795 lrwxrwirwx 1 root root 5 2011-09-08 00:59 softl -> filel 936796 lrwxrwxrwx 1 root root 5 2011-09-08 00:53 soft2 -> file2 f) Are contents of the 4 files the same? What command do you use to verify that? g) Create a hard link "file3" linked to "soft1". h) Use a text editor (Nano or VIM) to edit "soft2": change "hello" to "hello, world". Now, what is the content in each of the 5 files? Are they the same? What if you change the text in any of these files? i) Rename "file1" to "change". Now, how many files can you still open and view the content? Use the same command you used in step e) to view file information. What's the change? i) Use a text editor to edit "file3":type "Linux' and save. Now what will happen? Which files share the same content? Why? k) List all files you have now (use the option). Take a screenshot (#3-6) of the command and the result
