Question 1: Create demo account

To follow along with the examples shown here using the virtual machines is it safer to use an account other than the administration account (root). By pressing the button below a new account is created called "demo", password is also "demo". Log in using this account and you cannot do any damage. If you mess the account up and want to start again, just press the button again.

Once created, you can log into this account using telnet or ssh, logging into the hostname linuxzoo.net. Remember the username is demo and the password is demo. And remember, you cannot break anything using this account! The account begins with an empty directory, so dont be shocked that "ls" shows nothing...

MAKE SURE YOU USE THE USER demo. If you do this with "root" or another account, you will be marked wrong. If you start with the wrong user, make sure you delete any files you created wrongly before changing to demo.

Tests - not attempted
Create an account called demo, password demo UNTESTED

Question 2: cal

Use the cal command to find out which day the 31th of December 2002 was on. cal takes two parameters, the number of the month (e.g. 1 for January, 8 for August) and the year as a 4 digit number (e.g. 1997).

Enter the name of the day in the box below. For Monday enter "Mo", Tuesday is "Tu", Wednesday is "We", etc.

Enter the day:

Question 3: cal year

cal can also work with 1 parameter, which is the year. When given a year, it displays a calander for the whole year. Use this feature but redirect the output of cal so that the calander for 2005 is saved to a file called "yearfile" in the home directory of demo.

Tests - not attempted
yearfile exists in the right place UNTESTED
Create the calendar for 2005 in yearfile UNTESTED

Question 4: ls
