(Get a list from an NNTP server)
getlist [-AR] [-h host] [-p port] [list [pattern [types]]]
getlist obtains a list from an NNTP server and sends it to standard
output. list may be one of active (which is the default value),
active.times, distrib.pats, or newsgroups. active contains
a list of all newsgroups carried by the server with the high and low article
numbers in the group, and the group status field. active.times is a list of
newsgroups, their creation times (in seconds since epoch), and the creator
of the group. distrib.pats is a list of relevant distributions and
the newsgroups they apply to. newsgroups is a list of newsgroups
along with their short descriptions.
For more information on the formats of these files, see active(5), active.times(5), distrib.pats(5) and newsgroups(5).
The listing files other than the active file are common extensions to the
NNTP protocol and may not be available on all servers. For instance, counts
distributions, headers, moderators, motd, overview.fmt and
subscriptions, amongst other, may be available. Moreover, a uwildmat
pattern pattern may also be usable for some of these listing files.
For more information on the formats of these files, see distributions(5),
moderators(5), motd.news(5) and subscriptions(5). The overview fields
obtained with overview.fmt are the ones for which the overview database
is consistent (see extraoverviewadvertised in inn.conf for more
information). The list obtained with headers contains the fields
that can be retrieved using the HDR command (pattern can then be
either msgid or range). The list obtained with counts is like
the active one except that the number of articles in a newsgroup
is mentioned just before the flag of this newsgroup.
The pattern parameter may be used with a list value of active,
active.times or newsgroups to limit the output. If given, only
entries corresponding to newsgroups that match the uwildmat pattern
pattern will be printed.
If the list parameter is active, a third parameter, types, may
also be used to restrict the list. If given, only entries corresponding
to newsgroups with a newsgroup mode found in types will be printed.
For example, a types value of y would only show unmoderated groups,
and a types value of ym would show all unmoderated and moderated
groups but not aliased groups or groups that disallow postings.
Try to authenticate using the username and password information in passwd.nntp(5) before issuing the LIST command.
Connect to the server host rather than to the value of server in inn.conf or the value of the NNTPSERVER environment variable.
Connect to the port port, which is by default 119.
Try to switch to nnrpd with a MODE READER command before issuing the LIST request. It can be useful in case a feeding access exists for the news server: more information can be retrieved from nnrpd, compared with innd.
The following command will obtain the one-line descriptions of all newsgroups found on UUNET:
getlist -h news.uu.net newsgroups
The following command will show the active file entries for all moderated comp.* groups on the default server:
getlist active 'comp.*' m
The following command lists all groups where local postings are permitted, are moderated or aliased:
getlist active '*' ym=
Note that the wildcard character * has to be quoted by simple quotes
to protect it from the shell.
