Given a directory called Project1 with 500 files called rock000.py, rock001.py, ... , rock500.py, create a bash shell script that will rename all the files given in this directory. The script should take two arguments: a base name and a file extension. Please include the specifics from the example in the code (i.e., identify the base name, extension, and old and new file names and write them as part of the code). If we run bash project.sh project_rocks

Use the Bash shell for the completion of this project. Develop a shell scripting application that allows the user to perform some advanced mathematical operations. Your application should allow the user to perform these tasks: Task 1: Find the even multiples of any number chosen by the user in a given range – the user should specify the multiples of which number they want to print and a minimum and maximum value. The multiples printed should be within the [minimum, maximum] range. For example, if the user chooses the number 7 and would like to print all even multiples in the [15, 60] range, the program should print all the even multiples that are bigger than or equal to 15 (minimum), but smaller than or equal to 60 (maximum). The program should keep a count of how many numbers were printed and should output that count, as well as the numbers. The output then, for the example given, should be 28, 42, 56, and the count should be 3.
Make sure to do the proper exception handling in your code. Write shell script for a simple calculator which can perform basic arithmetic operations like addition, subtraction, multiplication or division depending upon the user input in Bash.Make sure to do the proper exception handling in your code.

Write a shell script that reads a file name and checks this file exists or not. If the file exists, searches this file for "Joshua" or "joshua" and displays the total number of occurrences of "Joshua" and "joshua"; if the file does not exists, display "the file does not exist." Hints: you can use cat and egrep.
Using PyCharm, create a new Project lab12. Under lab12 create a new Directory exercise,then create a Python file called name.py in which to writea class named Name. This class holds the entire name of a person, that is, first, middle and last names and a suffix, and keeps count of how many of these names are being used (this is explained below). 1. The class has the following fields: count, first, middle, last and suffix.2. The class has a constructor that receives one string parameter named name whose default value is an empty string (that is, calling the constructor with no parameters sets the value of name to an empty string). The constructor initializes all fields based on the value of name, as explained next: – The value of count depends on the number of words in name. For example,given the name Robert John Downey Jr then count is 4.– If name has one word then it has a first name.– If name has two words then it has a first and last names in that order.– If name has three words…
Write a bash script that accepts aperson’s name as a command-line argument and simply prints out the following greeting: "Good day, <name_entered>! Nice to meet you!", where <name_entered> is a positional parameter (i.e., a command-line argument) passed to the script. If the user does notenter a command-line argument when invoking this shell script, you will simply output: "Hope you have a great day!", without any name displayed. How to do this??
In this question, you will develop your own version of shell. Your shell will execute commands given bythe user. The steps involved will be as follows:1. User types a command, such as “cp ./OS ../newOS”. The command will be stored in a characterarray or a string object.2. Shell will perform tokenization and separate the command and its arguments.3. Shell will create a child process and use execvp system call to execute the command.4. Shell will wait for the command to finish execution.5. After the command has been executed, shell will ask the user to enter the command again.6. Shell will exit when the command given by the user is “exit”. 7. The command can have any number of | symbols, such ascommand1 | command 2 | command3 > file.txt

Write a bash script that would reside in the test directory, would take an integer as its sole command line argument, and would return a count of the number of project test cases involving exactly that many test files with extension ".bld". The test directory contains subdirectories which each have various numbers of test files in them. So the idea would be:E.g. ./countTests.sh 3 would count and return the number of test cases involving exactly three test files with extension ".bld"

CSE460 MID ASSIGNMENT Given the Linux shell command descriptions, please write down the corresponding shell commands in a terminal window. • Copy paste the shell commands(using Control+shift+C) to do the following • give screenshots so that I can understand b) Write a shell script, which first ask the user for a number. then, -> Print "Panther" if the number is divided by 10 but is neither a multiple of 4 and neither a multiple of 5. -> Print "Oodama_Rasengan" if the number is a multiple of 5 or 6, but not both. -> Print "Rasen_Shuriken" if the number is a multiple of both 5 and 6
