Assignment #7 - Managing Directories

Due Friday, October 14, 2022 (Section 1)

Due Wednesday, October 19, 2022 (Section 2)

In this assignment, you will create a file and directory structure, record it using a listing command and output redirection, and then change the structure and record its change with another listing command.a

• In your home directory, create a directory called filefest.
• Inside this directory filefest, create set of directories and files as shown in the following diagram. Use the Unix command mkdir to create a directory. Use whatever means you would like to make the files, such as output redirection or the Unix touch command. The contents of the files can be anything (or empty), but they must be plain text files, and you must use the exact names as shown in the diagram.

• In this diagram, there are three directories under filefest : pigstage, northgate, and rockstage. In pigstage, there are two files: kelly and nicole. In northgate, there is one file: john . In rockstage, there are two files --deni and kyle --and one directory, bleachers. In bleachers, there is one file, kevin . In the filefest directory, look at the directory structure you have created byr using the Unix list command ls -lR. Here is an example of how it looked. The pwd command at the start shows the present working directory, then follows the output of the ls -lR command.

  -----------------------------------------------------------------------------
  $ pwd
  /home/siegfried/public_html/cs275/stuff
  $ ls -lR
  .:
  total 3
  drwx------   2 johnd     users        4096 Mar  6 06:34 northgate
  drwx------   2 johnd     users        4096 Mar  6 06:33 pigstage
  drwx------   3 johnd     users        4096 Mar  6 06:34 rockstage
  
  ./northgate:
  total 0
  -rw-------   1 johnd     users           0 Mar  6 06:34 john
  
  ./pigstage:
  total 0
  -rw-------   1 johnd     users           0 Mar  6 06:33 kelly
  -rw-------   1 johnd     users           0 Mar  6 06:33 nicole
  
  ./rockstage:
  total 1
  drwx------   2 johnd     users        4096 Mar  6 06:34 bleachers
  -rw-------   1 johnd     users           0 Mar  6 06:34 deni
  -rw-------   1 johnd     users           0 Mar  6 06:34 kyle
  
  ./rockstage/bleachers:
  total 0
  -rw-------   1 johnd     users           0 Mar  6 06:34 kevin
  $
  -------------------------------------------------------------------------
  

• Still in the filefest directory, do the ls -lR command again, but this time redirect the output of this ls -lR command to a file called listing.
• Now move all the files in the directories pigstage (kelly and nicole), rockstage(deni and kyle), and bleachers (kevin) to northgate.
• Now delete the directories pigstage, rockstage, and bleachers.
• Once you have moved the files and deleted the directories, you would have this structure:

• Still in the filefest directory, use the ls -lR again to look at the new file structure you have.
• Still in the filefest directory, append the output of this ls -lR command to the file listing.
• Your assignment is to paste the contents of the file listing that you created into a file. This will show your directory and file structure "before" and "after" moving the files and deleting the directories.
• This file will be submitted on Moodle.
