Problem
1. Devise a script that takes a filename as argument (which must exist in the current directory) and looks in the home directory tree to display the listing of all its links. The listing should also be mailed to self.
2. Call up vi from a script so that every three minutes you hear a beep and see a message in the last line. This message appears in reverse video and reminds you to save the buffer. (Hint: Look up the man page of tput to know how to position the cursor. Set up a loop in the background and kill it when vi terminates.)
