NAME

       getlist - Get a list from an NNTP server

SYNOPSIS

       getlist [-AR] [-h host] [-p port] [list [pattern [types]]]

DESCRIPTION

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.

OPTIONS

       -A  Try to authenticate using the username and password information in passwd.nntp(5)
           before issuing the LIST command.

       -h host
           Connect to the server host rather than to the value of server in inn.conf or the value
           of the NNTPSERVER environment variable.

       -p port
           Connect to the port port, which is by default 119.

       -R  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.

EXAMPLES

       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.
