Write the above as part of your documentation in the script as comments Write a script that will do the following :.
1. Find out whether you are a root or not. Assuming that he root’s uid is 501.
2. Print the count of files and subdirectories in the specified directory.

The following points will be deducted if :
• Compilation Errors, missing electronic copy , missing the hardcopy , using recursion ( – 10 points )
• Logical Errors ( at least .5 points )
• Other ( .75 points ) if any of the following takes a place : • Unable to read the source code due to unclear printing • Incorrect program file name. • Hard copy is not stapled. • More than one hard copy per group ( if it is done as a group ). • Incorrect Style such as but not limited to Missing Header comments , missing footer , missing / incorrect serial number , missing / incorrect section number , not replacing my name with your name… etc.
Sample Run: The script starts her. Replace my first / last name with your first / last name
