Task $01(15$ points$)$ Task $02(15$ points$)$

Write a Bash script that takes an unspecified $($unlimited$)$ number of command$-$line arguments

$($parameters$),$ where each represents a filename. The script must iterate over each given

filename, check to see if the file exists, and if it does, display the number of lines in the file. If the

file does not exist, an appropriate error message should be displayed.

Use the shift command to allow for an unlimited number of filenames to be provided as

arguments.

In addition, if the script is run with no arguments provided, it should display a message to the

user with a hint as to how the command should be run $($sample syntax of the command usage$).$

Here is a screenshot of the expected behavior, testing all scenarios described above.

Write a Bash script that accepts an operator abbreviation and a list of integers as command line

argument $($parameters$)$ and performs the operation on the list of integers. The script should be

able to handle addition, subtraction, multiplication, division, exponentiation, and modulo.

Use a loop and the shift command to allow for an unlimited number of integers to be provided

as arguments.

A usage hint message must be displayed if the user enters no arguments and an error message

must be displayed if the user enters invalid arguments.

Here is a screenshot of the expected behavior, testing all scenarios described above. Replicate

this functionality in your script, including the formatting and outputs of all messages.
