Write a command-line tool called myfind that takes two arguments.The first is a starting directory to begin the search, and the second is a filename to locate. So, the command line $ myfind /Users proposal.doc /Users/stevekochan/MyDocuments/proposals/proposal.doc $ begins searching the file system from /Users to locate the file proposal.doc. Print either a full path to the file if it’s found (as shown) or an appropriate message if it’s not.
