nntpid – retrieve a single article from a news server
nntpid [ -v ] [ -d ] article [ article... ] nntpid [ -v ] [ -d ] nntpid [ -v ] -a newsgroup-name
nntpid makes a connection to a news server, retrieves one or more articles, and displays them.
You can specify the article you want by either:
nntpid will try to display the article using a pager (
more(1), unless you have specified an alternative in the environment variable
PAGER). This is partly for convenience, and partly a mild security measure: it gives you some protection against the news article potentially containing control sequences that cause unexpected behaviour in your terminal. If
nntpid detects that its standard output is not a terminal, however, it will bypass the pager and just write out the article directly.
There are a couple of alternative mode of operation. In one, enabled by the
nntpid retrieves all available articles in the group and writes them to standard output in
mbox format. In the other, enabled with
nntpid simply prints the lowest and highest article numbers currently available in that group from the news server.
The location of the news server is obtained by reading the environment variable
NNTPSERVER, or failing that the file
nntpid will attempt to interpret its argument list as specifying a series of news articles, as follows:
nntpidwill strip them off if it sees them, and will not complain if it does not. If the angle brackets are present, anything outside them will also be discarded.
For example, the following invocations should all behave identically. (Single quotes are intended to represent POSIX shell quoting, not part of the command line as it reaches
$ nntpid '<firstname.lastname@example.org>' misc.test 1234 $ nntpid 'email@example.com' misc.test:1234 $ nntpid 'wibble <firstname.lastname@example.org> blah' 'misc.test 1234'
nntpid is given no arguments at all, it will read from standard input. Every line it reads will be interpreted as described above, except that whitespace will also be trimmed from the start and end of the line first.
If you provide the
-a option (see below), none of the above applies. Instead,
nntpid will expect exactly one command-line argument, which it will treat as a newsgroup name.
nntpidwill log its entire conversation with the news server on standard error.
nntpidwill write the article straight to standard output without bothering to try using a pager.
nntpidwill always write straight to standard output (so the
-doption is unnecessary).
Currently, the only form of authentication supported by
AUTHINFO GENERIC, using the environment variable
NNTPAUTH. It will only attempt this if it receives a 480 response from the news server; if your news server never sends 480 then
nntpid will never even look at
