May I get help with this in bash shell. In this exercise, you will write a phone script which uses theconcepts we have learned in this course.You may use this script to create contact information and lookupphone numbers or remove phone numbers as shown below.The script you are going to write will invoke other scripts basedon your selections in a menu. Let's call the top script as phone.The phone script may have either zero, one or two parameters.If there is no parameter when you run phone script (i.e. if youjust run $ ./phone):It should have a menu as follows:1- Enter Information2- Search by Last Name3- Search by First Name4- Search by part of last name5- Display all phone numbers6- Get the email7- ExitPlease enter the choice:When the use enters a choice, then another script needs tobe executed.For example, when the user enters the first choice abovewhich is: 1- enter Information, a script must run that showsthe following lines:1- First Name:2- Last Name:3- Email:4- Cell Phone:5- Home phone6- Do you want to continue? Y/N :If the user enters Y, then the code should get theinformation of the next person.If you run the script with one parameter, then the code shouldcheck other information related to that parameter and displaythem. For example, if the parameter is the last name, the scriptshould display the phones and email of that person. In otherwords, if you run ($ ./phone Smith), the script rather thanshowing the above menu, it should display the phones and emailof Mr. Smith that you have in your contact list.If there are two parameters, the first parameter would be anoption. For example, d means delete and s means search. Inother words, if you run($ ./phone d Smith), the script must delete or remove Mr. Smithfrom the contact list.Additional work: You can add some awk or sed command thatenhance the phone script. Try to find out how these commandscan be applied to this application.

Use as many advanced python techniques as you can • Write classes to support the Decrypt and the Rotation algorithms.• Use Bitsets, Bytes, where bit manipulations are needed.• Use Regular Expressions to parse and search strings.• Write any supporting classes necessary to support the Decrypt and Rotation Algorithms.• For example, the Decrypt Algorithm needs support for reading an encrypted file.• The Decrypt class is only responsible for decrypting a character, NOT reading a file ANDdecrypting each character.
C++ coding assigment 5 I am having trouble to get my coding working because I addressBook.cpp and addressbook.h is not working well with my Person so I need help figure out the problem because I have don't know how to fix my coding so that both person and addressbook work for the main. remainder: due not type in java. Make sure to type c++ in different files like Main.cpp, Person.cpp, Person.j, AddressBook.cpp, and AddressBook.h This small project is geared to test your understanding of File IO. AddressBook Exception Create an AddressBookException class that you can use to throw exceptions in your address book. Your class should have a constructor that will allow you to set the particular message that corresponds to the error. You should use your custom exception class to throw an error in the findPerson method if the person being searched for cannot be found, in the getPerson method if the AddressBook is empty. You should also throw an error any time that the addressbook file that…

This function should read the information from the file (reversing what writeEmpToFile does), create a new employee and fill in the data. If the FILE has no more info (is at end of file), this function should return NULL. This function must also ensure any employee actually created (not the NULL) is added to the array (as is done in createEmployee). Change main to load employees from a file using a command called…

Need urgent help with Python Decorator creation Never used python decorator before Answer the following questions in the Python decorator context. Your answers should be written in a Markdown file. The quality of answers matters!! What is higher-order function and how it is different from functor? What are First-class objects? What is the significance of functions being First-class objects? What are inner functions? What is the major benefit of inner functions and why is it important for decorator Why @ symbol is called syntactic sugar? What's the biggest advantage of using it when decorators are used? How would it help Python's weak OOP encapsulation of Class? (Hint: google "Python @Property decorator")
