Write a script that takes user input. The person will input a username and the script will find/locate all files where that input is the owner of the file. You will need to verify that the input (username) exists in the passwd file. It is doesn't, the script will need to output "Username does not exist on this system!" and end the script. Redirect the output to a file that is named based on the username. For example, if a person enters bob for username, the file saved will be bob.txt. For example: Enter a username to search: ted Username ted does not exist on this system! Additionally, you will pipe the contents of the text file you created and append the number of lines at the bottom of the file. Save the script exercise8.sh and upload it to this assignment for credit.
