Once again, we're at the end of the lesson, time for a lap.
In this lesson, write a shell script that rewrites filenames to the filename in uppercase.
And the script must meet the following requirements.
The filename should be provided as an argument while running the script.
And if no argument was provided, the script should print an error message.
Do not use existing files, but use the touch command to create some dummy files before
running the script.
The purpose here is that you are not going to mess up the contents of your etc directory
or any other important files.
So just to be clear, the script shouldn't be creating the files, but before running
the script, you use touch file 1 and then you run the script to convert it to uppercase.
Good luck with that.
