Note: Utilize the Learning Module, the chmod Tutorial, and the supplementary material to answer the questions below. You are encouraged to use external resources to find the answers.


Susan's Homework

Susan is new to the command line, and does not quite understand file permissions. She has asked for your help so that she can finish her homework in time for class tomorrow morning.


Susan's professor has asked her to use the command line to back up a batch of files. She does not understand why she can't use a GUI program to back up these files.

1. Why might her professor be asking her to use a CLI to perform this operation? Please explain the possible reason(s) to Susan.


------------------------------------------------------------------------------------

Susan is viewing a directory on her computer. The directory listing is as follows: 

-rwx r-x r-x  susan  acctg  archive.sh 
-rw- rw- r--  susan  acctg  orgchart.gif
-rw- rw- r--  susan  acctg  homework.txt
-rw- r-- r--  susan  acctg  publicity.html
drwx rwx r-x  susan  acctg  sales
-rw- r-- ---  susan  acctg  topsecret.inf
-rwx r-x r-x  susan  acctg  wordmatic

2a. Susan's username is susan. She needs to make changes to homework.txt and save them. Is she able to do so?


------------------------------------------------------------------------------------

2b. Please explain why.


------------------------------------------------------------------------------------

3. What is the 3-digit numerical chmod of -rwx r-x r-x?


------------------------------------------------------------------------------------

Susan has read the chmod Tutorial, but is still confused. Click here to search with DuckDuckGo for an alternate resource on "file permissions".

4a. After you have picked the resource you think is best, list the web address (URL) and title of the resource.


------------------------------------------------------------------------------------

4b. Do you think this is a better resource than the chmod Tutorial? Why or why not?


------------------------------------------------------------------------------------

5. Please list any of the resources you may have used to answer the questions above.
