Write a basic BASH script. The script will be used to inspect a log file

Script Requirements

The script may be against a specific log file, or have the log file name determined by the command line. The student may determine which log file(s) or log file types to use as long as the log file contains at least 20 entries. Note: Many log files are available in /var/sys/log or /var/log.

The script will iterate through the log file and determine some useful information based on what it finds in the log file. This can be done using python as well (which i prefer)

These 3 tasks below should be performed within the bash file:

How many times did user X log in during a certain amount of time?

List the errors or failed attempts at an action.

Show new applications that were installed during a certain time frame.
