What are the steps required to be performed by the Ext2 file system subsystem to delete a file of size 72KiB? Assume you know and have in memory a copy of the inode of the directory the file is in and the inode of the file to be deleted. Also assume the block size is 1024 bytes. Either list the steps required or use a flowchart.

In an attempt to escape his island, Gilligan builds a raft and sets to sea. The wind shifts a great deal during the day, and he is blown along the following straight lines:

4.70 km 60° south of east; then
5.1 km straight east; then
7.2 km 55° south of west; and finally
2.8 km 10° north of east.

What is his final position relative to the island?

Who Pays, who Provides and who Measures US Healthcare?

The costs of healthcare are higher in the United States compared to any other developed country in the world, but this does not equate to best health status for our populations (OECD, 2018).

Creating a Perl Product Directory - A product "id" will be used to identify a product (the key) and the description will be stored as the value

• The program should print a menu asking you to "add" an entry, "remove" an entry, "lookup" an entry, "list" all entries, and "quit" to end
• The user will enter a number to select the menu item from above, 1, 2, 3, 4, or 5 respectively.

1. Asks the user to enter a product ID, then asks them to enter a description... the product ID is stored as the key of a hash and the description is the value
2. Asks the user to an ID, if that ID exists in the hash, that entry is deleted from the hash
3. Asks the user to an ID, if that ID exists in the hash, that entry's value is printed (the description)
4. Prints all the key/value pairs of the hash, each entry on a new line with with a colon or dash separating the ID from the description
5. Exits the program

• The program will continuously loop, that is, it will print the menu after each successful action... unless the user chooses 5 to quit, which will end the program. This can be achieved by either using a "while" loop or by using a subroutine that prints the menu after each successful action

Some code is provided to you as a template.

Go to your “Documents” directory;

a) Create a file “file1” with the text “hello” in it; Provide command and screenshot.

b) Create a hard link named “file2” linked to “file1”;

c) Create a soft link named “soft1” linked to “file1”; create another soft link named “soft2” linked to “file2”.

d) View information of the 4 files (what command should you use to produce output) – how do you verify which file is a hard link and which file is a soft link?

e) Use a text editor (Nano or VIM) to edit “soft2”: change “hello” to “hello, world”. Now, what is the content in each of the files? Provide screenshots. Are they all the same? If yes, why?

f) How do you remove all these hard and soft links? Apply the command and provide screenshots of the removal results.
