</div> <div title="Description">
---++ Description

Course accounts are able to cancel news articles to the course's uw.cs newsgroup with the *cancel-news* script.

<ul type="disc"> <li> articles may be canceled from the command-line by specifying the article number. </li> <li> articles may be canceled by piping the offending article (at least the headers) into *cancel-news*. </li> <li> the script will display the entire article in a pager (hit q to only show the first page). </li> <li> the user is normally required to confirm the cancellation with a Y or y followed by carriage-return.

<ul type="circle"> <li> a =-f= (or =--force=) parameter will "force" the cancellation with no article display, no confirmation; use with appropriate care. </li> </ul>
</li> <li> a =-d= (or =--dry-run=) parameter will do everything up until the actual cancel, to see what the program would do. </li> </ul>

Cancellations for articles which have reached external news providers (e.g. Google groups) may not be honoured by the external provider. UW has no control over what happens to news articles after they leave the campus.
