Bash Scripting Intro

1. Create a folder on your Linux server named a40bashcount. Make sure that your linux server has at least two user accounts and that the user accounts have at least a couple of files and folders (the names and contents of these files/folders are not important).
2. Write a bash shell script that takes the name of a user as a parameters and counts the number of files in that user's home folder (and sub-folders).
3. The output of the command should look similar to this:

   $ ./countfiles r.ford
   Report for files in r.ford home folder
   Home folder: /home/r.ford
   The user has 223 files/folders
                                           

   Please note that if you run this on an account that is not yours, you will likely see error messages. With some searching online, you should be able to find a way to supress the error message.
4. Some hints about what goes into the script. You can try the steps 2 and 3 on a command line by themselves before trying to use them in the script.
   1. Check to see if the parameter has been set and stop and print an error if it is missing.
   2. Get the home folder of the user from the /etc/passwd file. The grep and cut command will be helpful here.
   3. Once you know the user's home folder, you can use the find command to find everything and count them using wc.
5. If the user account does not exist then you should print a message like "User r.ford does not exist on this server".
6. When you are finished, show the contents of the script and show the script being run with a good user and a non-existing user.
