Could anyone help explain this?
1. The problem statement, all variables and given/known data:

I have a retake assignment to complete for my computer networks and OS class. This isn't really my area, had I known last year I could have swapped it for a different module I would have done so. I'm determined to get through it though.

Anyhow I digress. I am having trouble properly understanding the brief or where to begin it states:

"Monitoring a GNU/Linux system for changes:

For this referral assignment you are required to show how you might monitor important system directories in a GNU/Linux operating system for any changes in files or directories. Marks will be given as follows:

A) Provide an outline of which directories and files that you consider should be monitored for changes along with an indication of which changes you would monitor and how you would monitor them. ( up to 20%)

B) Provide a summary of available tools and utilities, both open source and commercial, that would help with this task. Your summary should include an indication of cost, complexity in
use and complexity in setup. ( up to 30%)

C) Develop a script or program that will implement at least some of the functionality required to support your analysis from (A). This script should keep a log of any changes found. The
script or program can be written in C, PERL, shell script or any other language that will execute on a GNU/Linux system. ( up to 50%)".


2. Relevant commands, code, scripts, algorithms:

N/A



3. The attempts at a solution (include all code and scripts):

I have a few theories and have been trying to do some research online but haven't found too much.

If anyone can help point me in the right direction it would be greatly appreciated.

4. School (University) and Course Number:

University of the West of England, Computing degree.

cal(1)								   User Commands							    cal(1)

NAME

       cal - display a calendar

SYNOPSIS

       cal [ [month] year]

DESCRIPTION

       The  cal  utility writes a Gregorian calendar to standard output. If the year operand is specified, a calendar for that year is written. If
       no operands are specified, a calendar for the current month is written.

OPERANDS

       The following operands are supported:

       month	Specify the month to be displayed, represented as a decimal integer from 1 (January) to 12 (December). The default is the  current
		month.

       year	Specify  the year for which the calendar is displayed, represented as a decimal integer from 1 to 9999. The default is the current
		year.

ENVIRONMENT VARIABLES

       See  environ(5) for descriptions of the following environment variables that affect the execution of cal: LANG, LC_ALL, LC_CTYPE,  LC_TIME,
       LC_MESSAGES, and NLSPATH.

       TZ    Determine the timezone used to calculate the value of the current month.

EXIT STATUS

       The following exit values are returned:

       0     Successful completion.

       >0    An error occurred.

ATTRIBUTES

       See attributes(5) for descriptions of the following attributes:

       +-----------------------------+-----------------------------+
       |      ATTRIBUTE TYPE	     |	    ATTRIBUTE VALUE	   |
       +-----------------------------+-----------------------------+

NOTES

       An  unusual calendar is printed for September 1752. That is the month 11 days were skipped to make up for lack of leap year adjustments. To
       see this calendar, type:

	 cal 9 1752

       The command cal 83 refers to the year 83, not 1983.

       The year is always considered to start in January.
