Modify rnfile such that it will keep a copy of the old existing file (if available) before the renaming operating. Assume that apple.txt will be renamed as orange.txt. When the command “./rnfile apple.txt orange.txt” is executed, the script will first check whether orange.txt exists under the given path or not. If the file exists then orange.txt will be renamed as orange.txt_old before renaming apple.txt as orange.txt. Make rnfile an executable shell script; try to rename a file to a filename that already exists. Show your shell program and its output to the instructor.

In Chapter 11, you created the most recent version of the MarshallsRevenue program, which prompts the user for customer data for scheduled mural painting. Now, save all the entered data to a file that is closed when data entry is complete and then reopened and read in, allowing the user to view lists of customer orders for mural types.
Please use javascript to write the function. write a function editDateTime() that runs when the Update button on the edit page is clicked. This function should confirm that the user wants to update the date and time shown, then take the value from the input area and update the user appointmentDateTime in the appointment, and update the appointmentList appointment to local storage. Then redirect the user to the view page using window.location.
A user wants to redirect a list to a file named users.txt. Identify the command line to implement this function. Choose an answer A ls > users.txt B cat > users.txt C ls < users.txt D ls 2> users.txt
The delivery drones have a internal reporting and logging system thatrecords events and issues during flights. These logfiles contain the last 1000events/messages as well as their status codes.The Logfile FormatBy default, the logfiles are all called ‘logfile.txt’. Each logfile is exactly 1000 lineslong.Each entry in the file consists of 4 fields:1. a line number (starting at 0)2. a POSIX timestamp3. a message/event type4. an event descriptionEach field (line number, timestamp etc.) is separated by a space, except for thedescription which ends with a full stop.Log events come in three different types: NOTIFY, WARNING, and ERROR. Task 1: Display Because the logfiles are so big, we would only like to display a certain number oflines at a time. We prompt the user to choose start and end line numbers andprint all the lines from start to end (inclusive).The input constraints are as follows: 0 start end 999You can safely assume that the inputs will fall within that…
Write the command taht will locate all files that have the suffix/extension of ".py". For each file that is located, the command should append the suffix/extension of ".backup" to the file. So, if a file had the name "one.py", its new name would be"one.py.backup".
The "-t" flag to "ls" sorts the listing by modification time. Write a BASH line which will write the name of file with the oldest modification time into a file called "lastfile".
modify minishell.c to run who, ls, and date with option. who will show the count of users, ls will list files in long listing format and date will show UTC time.

In this project, you should develop a library management system application using structuresand files. More specifically, your application should enable a user to read and write bookdetails to a file (books.txt). The file should store the following information for the books. Oneline per book and each field to be separated by tab.• Book ISBN• Book title• Author first name• Author surname• Year• Availability for loan [yes/no]The user of this application should have the following options in the form of a nice presentedmenu.Add a book: The user should add all the details of each book by answering a set of questions(book isbn? Book title? author? year?). The availability for loan is randomly generated by theprogram (y: yes, n:no). The book should be added at the end of the file.Search for a book: The user should be given three options here.▪ Search by the title: The user will input a keyword and the program willsearch for all the titles that contain this keyword and display all…
PLZ help with the following: Write a batch file where you will cycle trough colors A0, B0, C0, D0, E0, F0. You can use & to execute another command on the same line with a command. Use PAUSE so you may see the results one at a time. After viewing each color, press Spacebar until you cycle through the entire list of colors. You can use FOR command with the recursive switch (/R ) to execute a command in every directory within a directory folder , effectively “ walking the tree”, starting from the current directory or from another directory you specify and stepping down through each of the subdirectories. FOR /R %%A IN (list) DO command
