Need answer for these LINUX questions URGENT!!
I am very new to LINUX and could not find answer to these questions please submit your comments and suggestions to answer these questions.

Appreciate your time thank you, Smilie

1. Make sure there is no filename1.txt in current directory first. Now, enter vi with "vi filename1.txt" command. vi indicates that it is a new file. After you have completed entering text, you issue the VI command

:wq filename2.txt
to save and exit. Which file is created by VI editor? Explain.


2. Make sure there are no files called file1.txt and file2.txt in the current directory. Then, issue the following commands:
ln –s file1.txt file2.txt
ln –s file2.txt file1.txt
cat file1.txt
What is the error message you got? Explain why.

3. If you look at the permissions associated with a symbolic link, it has universal access. Does this lead to security issues? Why?


4. Review the man pages of ln, cp and mv commands. The synopsis section of the man pages contain the usage and the optional arguments are indicated within […]. From these 3 man pages, find out which command can work with just 1 argument. Give a sample usage and explain what it does.


5. Let us assume that Linux does not have .. entries in Linux directory structure. How will you cd to the parent directory of current directory? Note: Since current directory can be anything, you should give a generic answer (you should explain the process).

These are my answers I am not sure if I am doing it right though, your suggestions would be helpful,

Question 1:

Filename2.txt is created by VI editor. Although, filename1.txt was created it was never saved with the proper save syntax pointing to that file name. However with the :wq filename2.txt, it was overwritten to the filename1.txt when it was saved and exit.

Question 2:
The error message was, cat: file1.txt: Too many levels of symbolic links. I deleted using rm file1.txt and rm file2.txt to make sure there were no such file in the directory.

Question 5: I would assume using cd ..

please share your comments for these and other questions too.
