(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(3) 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(3) 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.
