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.

Using the Get-Help cmdlet will show us the help file of a cmdlet or topic. In this case, the Get-EventLog cmdlet. However, it is not showing the information on the parameters. How can we make it show the information on parameters
You are to implement removeHead, and removeTail and you also have to create the following functions (for visual purposes of the detail explanation, header and trailer sentinels are described as h and t respectively): IMPORTANT NOTE: For all the methods that has the pos parameter i.e. addAt, removeAt, move, make sure to access that specified position from whichever is nearer - the head or the tail - similar to what we have done in the get method. Example DoublyLinkedList: h <-> 10 <-> 30 <-> 40 <-> 50 <-> t int add(int num) This will add the element num into the last element of the linked list and return the position of the newly-added element. In the above example, having add(60) will return 5 as it is the fifth position in the list. int remove(int num) This will remove the first instance of the element and return the position of the removed element. In the above example, having remove(40) will return 3 as 40 was the third element in the linked list…
Answer the given question with a proper explanation and step-by-step solution. USING JAVA: ---Sorting the Invoices via dates--- Another error that will still be showing is that there is not Comparable/compareTo() method setup on the Invoice class file. That is something you need to fix and code. Implement the use of the Comparable interface and add the compareTo() method to the Invoice class. The compareTo() method will take a little work here. We are going to compare via the date of the invoice. The dates of the Invoice class are by default saved in a MM-DD-YYYY format. So they have a dash '-' between each part of the date. So you will need to split the date of the current invoice AND split the date of the object sent to the method. We have three things to compare against here. First we need to check the year. If the years are the same then you should go another step forward and compare the months. If the months are the same then you will lastly have to compare the day. Use whatever…
Add additional functionalites to this code. For one room add this riddle, "The shorter I am, the bigger I am. What am I?" And the only way to continue to the next room is to type, "A temper," or "temper." And for another room, a help command. For example, the user will type, "help," and they will be told where to go next so they can each the winning room.
PLEASE ENSURE TO USE THE FRAMEWORK PROVIDED IN THE IMAGES, AND THAT IT WORKS WITH THE TESTER CLASS. Write a class RangeInput that allows users to enter a value within a range of values that is provided in the constructor. An example would be a temperature control switch in a car that allows inputs between 60 and 80 degrees Fahrenheit. The input control has “up” and “down” buttons. Provide up and down methods to change the current value. The initial value is the midpoint between the limits. As with the preceding exercises, use Math.min and Math.max to limit the value. Write a sample program that simulates clicks on controls for the passenger and driver seats.
The acclaimed _NumPy_ library, that `Simpy` is inspired by, allows you to use the subscription operator not just to select individual items, but also to filter with a mask. It adds a second usage to the operator, just like you have had two uses of many of the operators above, such as adding two `Simpy`s or a `Simpy` and a `float`. The big idea of the second usage of subscription notation is that if instead of giving an `int` inside the subscription brackets you give a `list[bool]`, the expression will return a new `Simpy` object containing only the _masked_, or filtered, `values`. For example: ~~~python a = Simpy([1.0, 2.0, 3.0, 4.0, 2.0, 1.0]) mask = a > 2.0 print(mask) # Output: [False, False, True, True, False, False] b = a[mask] print(b) # Output: Simpy([3.0, 4.0]) ~~~ The above example did not need to establish a separate variable named `mask`, it only did so to make it obvious what the `mask` values were. More conventionally, the above example would be written in a…
It's messy that in the Balrog class's getDamage() function and the Cyberdemon class's getDamage() function we have to write the name of the species before calling the Demon class's getDamage() function. It would be better if the Demon class's getDamage() function could print the name of the species. Taking this a step further, it would be even better if we didn't have to repeat the cout statement "The <whatever> attacks for ?? points!" in every class's getDamage() function. It would be better if that cout statement could occur just once, in the Creature class's getDamage() function. In the Creature class's getDamage() function, insert the following statement:cout << "The " << getSpecies() << " attacks for " << damage << " points!" << endl; Delete (or, if you prefer, comment out) the similar cout statements that appear in the getDamage() function of each of the 5 derived classes. (There will be one such cout statement to delete in each of the 5…

You are given a list of projects and a list of dependencies (which is a list of pairs of projects, where the second project is dependent on the first project). All of a project's dependencies must be built before the project is. Find a build order that will allow the projects to be built. If there is no valid build order, return an error.EXAMPLEInput:projects: a, b, c, d, e, fdependencies: (a, d), (f, b), (b, d), (f, a), (d, c)Output: f, e, a, b, d, c

Using appdesigner in Matlab, please write a very simple and short GUI where there is one button in the main GUI screen. When you click on this button, it changes the text of itself to your name. If you can make this change continuous, meaning if you keep on clicking on the button the text will iterate between "Button" and "your name", that will be superb !!!
