Kali virtual machine

Create one script does one of two things. It either creates a backup of your directory or performs a security check to be sure the files have not been changed without you knowing.

Your script must do the following:

1) If the user wishes, it performs a backup of your home directory structure.

2) If the user wishes to do a security check, the script checks if any files in a directory have changed (use sha1sum and diff). You will need to create a temporary file to hold the new data so you can compare the two.

Your code should also do the following:

Create a maintenance log of who (username) and when (date) the hash checks were completed. Store the date and name in a file called maintenance. If the file already exists the code should append to the end.

• Make sure you check to be sure if you can read the file and you can write to it before doing it. If you can’t print out an error.

• The script should print out the name of the file(s) that changed and its old and new hash.

• Prove that your code works.

I have an incomplete code please help me.
