Part I: getopt_long (6 marks) Following the getopt_long demo posted on the course web site, modify your getopt and test your program from Lab1 so that it accepts long options. Make up your own long option names if there is no equivalent in the man page. Any long option names you create should reflect the meaning of the flag, as described in the man page. Add and test a long option where the has_arg entry has a value of 2, that is your flag will take an optional argument, especially if you did not do this exercise in Lab 1 The only change you have to do is make is to create and initialize your own version of the struct options array then create and run a script to test your long arguments. Hand in: Full listing, script, status of testing.
