Selecting a Group on Which to Operate
Selecting a Group on Which to Operate
When the user selects a newsgroup to browse, the newsreader may tell the news server that the group was selected. This simplifies the interaction between newsreader and news server; it removes the need to constantly send the name of the newsgroup with each command. The group command simply takes the name of the selected group as an argument. Many following commands use the group selected as the default, unless another newsgroup is specified explicitly:
group junk
211 3 1 3 junk
The group command returns a message indicating the number of active messages, the low-water mark, the high-water mark, and the name of the group, respectively. Note that while the number of active messages and the high-water mark are the same in our example, this is not often the case; in an active news server, some articles may have expired or been deleted, lowering the number of active messages but leaving the high-water mark untouched.
