NNGREP(1) UNIX System V (Release 6.5) NNGREP(1)
NAME
nngrep - grep for news group names (nn)
SYNOPSIS
nngrep [ -ainprsu ] [ -l ] [ pattern ]
DESCRIPTION
nngrep can print various selections of the available news
groups.
Without options, nngrep will list all currently subscribed
newsgroups whose name matches any of the specified patterns.
If no pattern is specified, all subscribed groups will be
listed.
The selection of news groups against which the patterns are
matches, and subsequently printed by nngrep can be limited
or expanded using the following command line options and
arguments:
-a Use both subscribed and unsubscribed groups. Overrides
the -u option.
-i Use only ignored groups, i.e. which are not in the
presentation sequence.
-n Use only new groups. Notice that nn considers a group
to be new until you have read at least one article in
the group, or you have unsubscribed to the group. This
means that even reasonable active news groups may
remain "new" for quite some time if it only contains
articles which are cross-posted to other groups which
occur earlier in your presentation sequence.
-p Use only groups with unread (pending) articles.
-r Use only read groups, i.e. without unread articles.
-s Use only groups which are in the presentation sequence.
-u Use only unsubscribed groups.
These options can be combined if they don't logically
exclude each other.
For example, to get the names of all "source" groups, you
can use the command
nngrep source
You can use this to read a specific subset of news groups
with nn; for example
nn `nngrep -sp source`
