| 18 | \U DESCRIPTION |
| 19 | |
| 20 | \cw{nntpid} makes a connection to a news server, retrieves one or |
| 21 | more articles, and displays it. |
| 22 | |
| 23 | You can specify the article you want by either: |
| 24 | |
| 25 | \b giving its Message-ID. Message-IDs are globally unique, so you |
| 26 | don't need to know which newsgroup the article was in. Also, they do |
| 27 | not vary between news servers. |
| 28 | |
| 29 | \b giving a newsgroup name and an article number within that |
| 30 | newsgroup. Article numbers are assigned internally by a particular |
| 31 | news server, so they will be different on other servers carrying the |
| 32 | same group. |
| 33 | |
| 34 | By default, \cw{nntpid} will try to display the article using a |
| 35 | pager (\cw{more}(1), unless you have specified an alternative in the |
| 36 | environment variable \cw{PAGER}). This is partly for convenience, |
| 37 | and partly a mild security measure: it gives you some protection |
| 38 | against the news article potentially containing control sequences |
| 39 | that cause unexpected behaviour in your terminal. If \cw{nntpid} |
| 40 | detects that its standard output is not a terminal, however, it will |
| 41 | bypass the pager and just write out the article directly. |
| 42 | |
| 43 | There is a third mode of operation, enabled by the \cw{-a} option, |
| 44 | in which \cw{nntpid} retrieves \e{all} available articles in the |
| 45 | group and writes them to standard output in \cw{mbox} format. |
| 46 | |
| 47 | The location of the news server is obtained by reading the |
| 48 | environment variable \cw{NNTPSERVER}, or failing that the file |
| 49 | \cw{/etc/nntpserver}. |
| 50 | |
| 51 | \U ARGUMENTS |
| 52 | |
| 53 | If you specify one argument, \cw{nntpid} assumes it is a Message-ID. |
| 54 | The angle brackets that usually delimit Message-IDs are optional; |
| 55 | \cw{nntpid} will strip them off if it sees them, and will not |
| 56 | complain if it does not. |
| 57 | |
| 58 | If you specify two arguments, \cw{nntpid} will interpret the first |
| 59 | as a newsgroup name, and the second as an article number. |
| 60 | |
| 61 | \U OPTIONS |
| 62 | |
| 63 | \dt \cw{-v} |
| 64 | |
| 65 | \dd Verbose mode. In this mode, \cw{nntpid} will log its entire |
| 66 | conversation with the news server on standard error. |
| 67 | |
| 68 | \dt \cw{-d} |
| 69 | |
| 70 | \dd Direct output. In this mode, \cw{nntpid} will write the article |
| 71 | straight to standard output without bothering to try using a pager. |
| 72 | |
| 73 | \dt \cw{-a} |
| 74 | |
| 75 | \dd Retrieve all articles from the given newsgroup. In this mode, |
| 76 | \cw{nntpid} will always write straight to standard output (so the |
| 77 | \cw{-d} option is unnecessary). |
| 78 | |
| 79 | \U AUTHENTICATION |
| 80 | |
| 81 | Currently, the only form of authentication supported by \cw{nntpid} |
| 82 | is \cw{AUTHINFO GENERIC}, using the environment variable |
| 83 | \cw{NNTPAUTH}. It will only attempt this if it receives a 480 |
| 84 | response from the news server; if your news server never sends 480 |
| 85 | then \cw{nntpid} will never even look at \cw{NNTPAUTH}. |
| 86 | |
