Can you help in linux bash coding, and can you please make the sample input also, and state how to make the sample input please.

Create a script where the script takes one argument, and the value provided will be a user. Loop through each file in that user's home directory (ignore the sub directories) and create a backup of that file in /bkp if the file doesn't already exist in /bkp add the date in the format yyyy-mm- dd (hint use the 'date' command) to the end of the file name saved in /bkp. Once completed, take a screenshot of the source code of the script, and of the script executing, to execute the script you will need to create your own sample input, please include the sample input as part of your execution screenshot
