IT101-Homework 2
5. In your AFS file space, do the following:
a. (2pts) Change the permissions on your home directory and the IT101 directory (see in class lab), so
that I (UCID llw2) can list and read your files. In your homework WORD document, type the
command you used to make this permission change.
b. (2pts)In your under the \"IT101\" directory, make a new directory called \"homework2\" using mkdir.
(It should automatically inherit the permissions from your home directory if you did step 5a first
otherwise you will need to change permissions manually on homwork2). In your homework WORD
document, type the commands you used to show the afs and UNIX permissions for homework2.
c. (4pts)Create a short text file containing your name and major. Name the file IT101-HW2.txt and
place it in your homework2 directory. It is probably easiest to create the file on your usual
computer and then use MobaXterm to transfer the file to AFS. Use notepad or wordpad, not Word,
to create the file.
d. (1pts) Use pwd to get the absolute path to directory homework2
Write the absolute path to directory homework2 into the WORD document you submit for this
homework. I will grade this problem by trying to read your file, so double-check that the path is correct.
