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(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.

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.
