- Write a utility program that combines the files together into anew file using the following command:java Exercise17_12 SourceFile1 . . . SourceFilen TargetFileThe command combines SourceFile1, . . . , and SourceFilen into TargetFile.You work for a small company that keeps the following information about its clients:• first name• last name• a 5-digit user code assigned by your company.The information is stored in a file clients.txt with the information for each client on one line(last name first), with commas between the parts. For exampleJones, Sally,00345Lin ,Nenya,00548Fule,A,00000Smythe , Mary Ann , 00012Your job is to create a program assign usernames for a login system.First: write a function named get_parts(string) that will that will receive as its arguments astring with the client data for one client, for example “Lin ,Nenya,00548”, and return theseparate first name, last name, and client code. You should remove any extra whitespace from thebeginning and newlines from the end of the parts.You’ll need to use some of the string methods that we covered in this lessonYou can test your function by with a main() that is just the function call with the argument typed in.Second: write a function make_user(param)…For example, if you create a file named: "users.txt" that contains these user names: daniel moshe yossy gabi ran bijo baruch bibi The following command run in an elevated command prompt will parse this file, and create a new user on your computer FOR /F %i in (users.txt) DO NET USER %i P@ssw0rd /ADD With two (2) other options that you specify for each user when they are added?

- Answer the questions in Linux command 1. Create a single command to read a file called program.c and write a file called unreadable.c, by replacing all newlines and tabs with spaces, and replacing all multiple consecutive spaces with a single space. The result should still be a legal C program but not exactly readable. 2. Write a single shell command line, possibly consisting of multiple commands (separated by semicolons), that will create a file diffs.txt containing a list of all files found in my Documents directory that aren’t also found in yours. Assume your current working directory is your home directory.I have an issue with trying to modify my code, I need to instead to work such that a user imputs a file paths and the program synchronizes themthe code is too long to post so I have placed it belowhttps://github.com/Philanthropenos/2023-final-work-for-os-class/blob/main/Attempt1.1Suppose you have Java source files under the directorieschapter1, chapter2, . . . , chapter34.

- Why is it considered good practice to open a file from within a Python script using (a) instead of (b)? (a) with open(‘textfile.txt’,’r’) as f: f.readlines() (b) f=open(‘textfile.txt’,’r’) f.readlines() f.close() a. When you open a file using the with keyword in Python, Python will make sure the file gets closed, even if an exception or error is thrown. b. The with keyword lets you choose which application to open the file in. c. The with keyword acts like a for loop, and lets you access each line in the file one by one. d. There is no benefit to using the with keyword for opening a file in Python.Please complete these files. There are two text files attached.
