shell scripting

only task 2 number 4 , 5 

Task I (for January 12) 1. In your home directory somewhere on your home directory (either on macOS or Linux), create a directory named breakfast 2. Change to the breakfast folder. 3. Create two empty files, file1.txt and file2.txt. 4. Randomly copy three more files into this folder, text file or not. (If you need text files, copy them from http://www.textfiles.com/directory.html ) 5. Create a directory named messy 6. Create an empty file file3.txt. 7. Add a few lines of text to this file. (If you don't feel like searching, use http://www.textfiles.com/humor/COMPUTER/aliceunix.txt just for fun.) 8. Randomly copy two more files into this folder. Task II (for January 17) Change to the breakfast folder. Then complete the following tasks by writing shell commands at the prompt: 1. Check if a file exists. Print a message stating if the file exists or not. 2. Read from a given text file and print the content on the screen with one blank line after each line in the file (like double-spacing the content). Make sure your script checks if the file exists before the actual operation. If not, report the error. Test this script with messy/file3.txt. 3. List the path of all files (no directory) in the working directory non-recursively using a for loop (without using Is or find). 4. List the size and path of all files in the working directory non-recursively using find. 5. List the path of files with the extension "txt" in the home directory.
