26 \fIbbc\fR is a BBoard
|
|
|
27 reading/checking program that interfaces to the BBoard
|
|
|
28 channel.
|
|
|
29
|
|
|
30 The \fIbbc\fR program has three action switches which direct its operation:
|
|
|
31
|
|
|
32 The `\-read' switch invokes the \fImsh\fR program on the named
|
|
|
33 \fIBBoards\fR. If you also specify
|
|
|
34 the `\-archive' switch, then \fIbbc\fR will invoke the \fImsh\fR program on
|
|
|
35 the archives of the named \fIBBoards\fR. If no \fIBBoards\fR are given
|
|
|
36 on the command line, and you specified `\-archive',
|
|
|
37 \fIbbc\fR will not read your `bboards' profile entry, but will
|
|
|
38 read the archives of the \*(lqsystem\*(rq \fIBBoard\fR instead.
|
|
|
39
|
|
|
40 The `\-check' switch types out status information for the named \fIBBoards\fR.
|
|
|
41 \fIbbc\fR
|
|
|
42 can print one of several messages depending on the status of both the
|
|
|
43 BBoard
|
|
|
44 and the user's reading habits.
|
|
|
45 As with each of these messages, the number
|
|
|
46 given is the item number of the last item placed in the
|
|
|
47 BBoard.
|
|
|
48 This number (which is marked in the messages as the \*(lqBBoard\-Id\*(rq) is
|
|
|
49 ever increasing. Hence, when \fIbbc\fR
|
|
|
50 says \*(lqn items\*(rq, it really means that the highest BBoard\-Id is \*(lqn\*(rq.
|
|
|
51 There may, or may not actually be \*(lqn\*(rq items in the BBoard.
|
|
|
52 Some common messages are:
|
|
|
53 .in +1i
|
|
|
54
|
|
|
55 .ti -.5i
|
|
|
56 \fBBBoard \-\- n items unseen\fR
|
|
|
57 .br
|
|
|
58 This message tells how many items the user has not yet seen.
|
|
|
59 When invoked with the `\-quiet' switch,
|
|
|
60 this is the only informative line that \fIbbc\fR will possibly print out.
|
|
|
61
|
|
|
62 .ti -.5i
|
|
|
63 \fBBBoard \-\- empty\fR
|
|
|
64 .br
|
|
|
65 The BBoard is empty.
|
|
|
66
|
|
|
67 .ti -.5i
|
|
|
68 \fBBBoard \-\- n items (none seen)\fR
|
|
|
69 .br
|
|
|
70 The BBoard has items in it, but the user hasn't seen any.
|
|
|
71
|
|
|
72 .ti -.5i
|
|
|
73 \fBBBoard \-\- n items (all seen)\fR
|
|
|
74 .br
|
|
|
75 The BBoard is non\-empty, and the user has seen everything in it.
|
|
|
76
|
|
|
77 .ti -.5i
|
|
|
78 \fBBBoard \-\- n items seen out of m\fR
|
|
|
79 .br
|
|
|
80 The BBoard has at most m\-n items that the user has not seen.
|
|
|
81 .in -1i
|
|
|
82
|
|
|
83 The `\-topics' switch directs \fIbbc\fR to print three items about the named
|
|
|
84 \fIBBoards\fR:
|
|
|
85 it's official name,
|
|
|
86 the number of items present,
|
|
|
87 and the date and time of the last update.
|
|
|
88 If no \fIBBoards\fR
|
|
|
89 are named, then all BBoards
|
|
|
90 are listed. If the `\-verbose' switch is given, more information is output.
|
|
|
91
|
|
|
92 The `\-quiet' switch specifies that \fIbbc\fR should be silent if no
|
|
|
93 \fIBBoards\fR are found with new information.
|
|
|
94 The `\-verbose' switch specifies that \fIbbc\fR is to consider you to be
|
|
|
95 interested in \fIBBoards\fR that you've already seen everything in.
|
|
|
96
|
|
|
97 To override the default \fImshproc\fR and the profile entry,
|
|
|
98 use the `\-mshproc\ program' switch.
|
|
|
99 Any arguments not understood by \fIbbc\fR are passed to this program.
|
|
|
100 The `\-protocol' switch tells \fIbbc\fR that your \fImshproc\fR knows about
|
|
|
101 the special \fIbbc\fR protocol for reporting back information.
|
|
|
102 \fImsh\fR\0(1), the default \fImshproc\fR, knows all about this.
|
|
|
103
|
|
|
104 The `\-file\ BBoardsfile' switch tells \fIbbc\fR to use a non\-standard
|
|
|
105 \fIBBoards\fR file when performing its calculations.
|
|
|
106 Similarly, the `\-user BBoardsuser' switch tells \fIbbc\fR to use a
|
|
|
107 non\-standard username.
|
|
|
108 Both of these switches are useful for debugging a new \fIBBoards\fR or
|
|
|
109 \fIPOP\fR file.
|
|
|
110 @BEGIN: BPOP
|
|
|
111
|
|
|
112 If the local host is configured as a POP BBoards client,
|
|
|
113 or if the `\-host\ host' switch is given,
|
|
|
114 then \fIbbc\fR will query the POP service host as to the status of the BBoards.
|
|
|
115 The `\-user\ user' switch then takes on a new meaning:
|
|
|
116 it refers to the name of the guest account for BBoards on the service host.
|
|
|
117 The `\-rpop' switch uses the UNIX \fIrPOP\fR
|
|
|
118 (authentication done via trusted connections).
|
|
|
119 In contrast, the `\-norpop' switch uses the ARPA \fIPOP\fR
|
|
|
120 (in which case \fIbbc\fR will prompt for a password,
|
|
|
121 unless the \-user specifies the guest account).
|
|
|
122 @END: BPOP
|
|
|
123 @BEGIN: NNTP
|
|
|
124
|
|
|
125 If the local host is configured as an NNTP BBoards client,
|
|
|
126 or if the `\-host\ host' switch is given,
|
|
|
127 then \fIbbc\fR will query the NNTP service host
|
|
|
128 as to the status of the BBoards.
|
|
|
129 For NNTP BBoards clients,
|
|
|
130 the `\-user\ user' and the `\-rpop' switches are ignored.
|
|
|
131 @END: NNTP
|
|
|
132
|
|
|
133 The \fI\&.bbrc\fR file in the
|
|
|
134 user's \fB$HOME\fR directory
|
|
|
135 is used to keep track of what messages have been read.
|
|
|
136 The `\-rcfile\ rcfile' switch overrides the use of \fI\&.bbrc\fR for
|
|
|
137 this purpose.
|
|
|
138 If the value given to the switch is not absolute,
|
|
|
139 (i.e., does not begin with a \fB/\fR\0),
|
|
|
140 it will be presumed to start from the current working directory.
|
|
|
141 If this switch is not given (or the `\-norcfile' switch is given),
|
|
|
142 then \fIbbc\fR consults the envariable \fBMHBBRC\fR,
|
|
|
143 and honors it similarly.
