When you use a computer, you are in effect renting time on it, the cost of which is charged to a project number. At the University of Delaware, you may be authorized to use several projects. For example, most students are authorized to use an email account which has project number 4000. You are now also authorized to use the CISC181 class project for doing computer work for this course.

Whenever you log on, the computer time that you use is automatically charged to a project called your default project. If you have an email account, probably project 4000 is your default. Check to see what project numbers you are authorized to charge your time against and which of these is your default project by typing the Unix command chdgrp. Here is an example execution: 

strauss.udel.edu% chdgrp     
Project    Title                 Remaining      Valid on hosts
 2024   CISC181440                 6000.00       brahms
 4000   U. OF D. E-MAIL              50.00       brahms

default group is currently 4000
In the above case, the user is authorized to use either of these two projects, and the user's default project when they logon is currently 4000.

If the CISC181 project number is not included in your list, it may be because you have just registered for the course very recently. This is normal. Try it again in 24 hours.


  • Type the command chdgrp 2024. This will change the default project so that you will be working on project 2024 automatically each time you log on in the future. Note: it takes up to 24 hours for your old default project to be replaced by the new one. An example is shown below. 

        strauss.udel.edu% chdgrp 2024
    Changing default project for cfischer
