==Overview==
Most system administrators would like to know the utilization of their systems by their users. On a Linux system, the userseach user' s login records are normally stored in the binary file /var/log/wtmp. The login records record in this binary file can not be viewed or edited directly using normal Linux text commands like 'less', 'cat', etc. The 'last' command is often used to display the login records stored in this file in a human readable form. Please check the man page of the 'last' command for available options. The following listing is a sample output of running the 'last' commandwith the '-F' flag on:
<pre>
$ last -F
...
</pre>
In this assignment, your task is to create a python program with well designed functions to produce daily, weekly, and monthly usage report reports by user (and/or by other criteria) remote host based on the information obtained from the 'last' command or given files which contain similar information as the 'last' command.

=== Program Name and valid command line arguments ===
Name your Python3 program as <code>usage_reportur.py</code>. The program should accept the following one or more "file name" as its command line parametersand other optional parameters as shown below. Your ur.py script should produce the following usage when run with the --help option:* <b><codepre>[rchan@centos7 a1]$ python3 ./ur.py -husage: ur.py [-h] [-l {user</code></b> or <b><code>,host}] [-r RHOST] [-u</code></b> as an optional first argumentt {daily,weekly, followed by:monthly}]* <b><code>filename</code></b>, or [-u USER] [-v]* <b><code>filename1 filename2 </code></b> etc . F [F .. - any number of filenames from 1 to as many as the command-line supports.]
optional arguments: -h, --help show this help message and exit -l {user,host}, --list {user,host} generate user name or remote host IP from the given files -r RHOST, --rhost RHOST usage report for the given remote host IP -t {daily,weekly,monthly}, --type {daily,weekly,monthly} type of report: daily, weekly, and monthly -u USER, --user USER usage report for the given user name -v, --verbose tune on output verbosity Copyright 2018 - Raymond Chan </pre>Replace the last line with your own full name If one of the file name given is "last", your python program should get the login records from the 'last' command with the appropriate flags. If there is one file name provided at the command line, read the login records from the contents of the given file. The format of each line in the file should be the same as the output of 'last -Fiw'. If there is more than one filename file name provided, merges all the files together with the first one at the top and the last one at the bottom. Read and process the file contents in that order in your program.
