Script: You will write a basic script to create and back up files. You will create this script with the vi editor. The script will combine multiple commands and simplify a repeatable task. Your script should be named Firstname_Lastname. BASH. Your script and your Linux directory structure should demonstrate that you have correctly written the script to do the following: 1. Create files: In this section, you will demonstrate your ability to utilize various Linux commands to create text files. Create these files in the NEW directory. Ensure that the commands in your log file show that the following three text files were created using three different methods.
Create the following files:
A. A text file listing the quantity of operating system free space, titled Free_Space_Content. txt
B. A text file listing the directory contents of the OLD folder, titled OLD_Content. txt
C. A text file showing the current month, day, and time (Title this file Time_File. txt.)
2. Modify and Move files: Utilize Linux commands to copy files to a different directory and rename them.
A. Copy the following selected files from the OLD directory to the BACKUP directory. Ensure that you change the filename suffix from XXX_OLD to XXX_BACKUP.
i. Free_Space_Content_OLD. txt
ii. Directory_Content_OLD. txt
iii. Time_File_OLD. txt
B. Move all files from the NEW directory to the BACKUP directory (no renaming necessary). Clean up the Linux directory structure by deleting the items in the NEW directory.
3. Execute the script: At this point, you will need to complete and execute the newly created script and complete a successful directory backup process.
4. Assess output: Finally, analyze the Linux directory structure and file contents to confirm successful script implementation. Ensure that you download your script and your Script_Assessment. txt file for submission.

Me2540 week 5 assignment what do i want to know?

How can i clip a picture to a question on the computer?

1. package newton’s method for approximating square roots (case study 3.6) in a function named newton. this function expects the input number as an argument and returns the estimate of its square root. the script should also include a main function that allows the user to compute square roots of inputs until she presses the enter/return key. 2. convert newton’s method for approximating square roots in project 1 to a recursive function named newton. (hint: the estimate of the square root should be passed as a second argument to the function.) 3. elena complains that the recursive newton function in project 2 includes an extra argument for the estimate. the function’s users should not have to provide this value, which is always the same, when they call this function. modify the definition of the function so that it uses a keyword parameter with the appropriate default value for this argument, and call the function without a second argument to demonstrate that it solves this problem. 4. restructure newton’s method (case study 3.6) by decomposing it into three cooperating functions. the newton function can use either the recursive strategy of project 1 or the iterative strategy of case study 3.6. the task of testing for the limit is assigned to a function named limitreached, whereas the task of computing a new approximation is assigned to a function named improveestimate. each function expects the relevant arguments and returns an appropriate value. 5. a list is sorted in ascending order if it is empty or each item except the last one is less than or equal to its successor. define a predicate issorted that expects a list as an argument and returns true if the list is sorted, or returns false otherwise. (hint: for a list of length 2 or greater, loop through the list and compare pairs of items, from left to right, and return false if the first item in a pair is greater.)
