EE-WEB Assignment 9

Program 1, 30pts.

Write a program in PERL that runs under Unix (on cegt201 or other machine. The program should run the Unix command last and tap to its output (use of pipeline to read). The program should track how many time each user logged in, and produce (print to the screen) a table sorted in the descending order. Use of a hash table to count user log ins is suggested.

Since it is your first assignment in PERL please check as soon as possible if you can run programns in PERL even if you plan to work on this assignment later. Submitting the correct program by the non-extended deadline may require some reading ahead but it will result in a small extra credit.
