- Computer Science Bash Assignment: Write a script that: Prompts the user for a directory name (Note that . means current directory) Lists the executable files contained in the provided directorylinux !#bin/bash Backup Files Write a bash script to backup files. The script can take 0, 1 or 2 arguments. When there are 0 or more than 2 arguments, the script should print out the usage of the program on the screen. When there is 1 argument, the program should take the argument as source directory and backup all the files (not include directories) in the source directory. If the source directory does not exist, the program should print out the error message and the usage of the program on the screen. If the source directory exist, create a subdirectory inside source directory named ”backup-yyyy-mm-dd” and copy all the files in sourceWrite a bash script for a menu driven file management utility that can do following operations Create file Delete file Copy file Move file Change file user and group owner Change file permissions
- Write a bash script for a menu driven file management utility that can do following Create file Delete file Copy file Move file Change file user and group owner Change file permissionsLinux bin bash script to create a new user on your Linux system and assign the user to a group. The script will first check if the user and group exists. If the user exists, provide a message saying the user exists. If the user doesn’t exist, create the group, if it doesn’t exist, and then create the user, finally assign the user to the group. Move the script to /home//scripts/ directory. Change the group to techstaff. Set appropriate permissions.Create a simple login form using Java Swing Create an RMI application with GUI that will allow users to log in and log out. Please store the credentials in a JSON file (username and password). The program will use this file to verify the user and allow them access to the application.
- To view the help files of a cmdlet, we can use all of these cmdlets/alias/function, except: Group of answer choices LS Get-Help MAN HELPInstructions Your job is to write a program to encrypt outgoing messages and decrypt incoming messages using a Vigenere Cypher. In this assignment, you will parse a string of words from a file into tokens using the strtok_s command with pointers and then use the Vigenere Cypher algorithm to encrypt and decrypt the parsed words. Before you can perform any encryption/decryption activities, the first step is to read in messages from a file and parse the messages into individual words. The Program: Setting up classes and understanding tokenization The first step in encrypting/decrypting messages is to parse the messages into words before applying the encryption/decryption algorithms to them. This parsing process is called “tokenization.” Read the contents of a file into this array using the getline command. The objective of this assignment is to demonstrate the use of pointers in a program utilizing c-strings and tokenization. The use of pointers is foundational in C++.
