24 \appendix{A}{MH Commands}
25 \MH/ is composed of several \unix/ programs,
26 which in theory are fairly simple and single-purposed.
27 These commands are functionally grouped below:
29 \psect{Composing Mail}
30 \pitem{comp} compose a message.
31 A program to originate a message.
32 Usually, a special prompting editor front-end, \pgm{prompter},
33 is used to fill-in a composition template with the addressees of
34 the message, subject, and so forth.
36 \pitem{dist} redistribute a message to additional addresses.
37 A program that re-enters a message previously received by the user
38 into the message transport system.
39 Only new addresses are added;
40 the body of the message is not changed in any way.
42 \pitem{forw} forward messages.
43 A program that encapsulates one or more messages in a new message draft.
44 In addition, the user may add initial and/or closing comments.
46 \pitem{repl} reply to a message.
47 A program that constructs a reply to a message using a reply template.
48 The template mechanism has sufficient generality to permit the user to
49 ``program'' the form of the reply draft based on the contents of the message
52 \pitem{send} send a message.
53 A program that posts a draft with the message transport system.
54 The \pgm{send} program is
55 usually invoked by one of the four preceding programs,
56 and performs simple front-end pre-processing prior to invoking the
59 if invoked in {\it push}'d mode,
60 \pgm{send} will immediately relinquish control of the user's terminal and
61 post the message in the background.
63 \pgm{send} will send back a failure notice to the user.
64 If the user had \pgm{push\/}'d the sending of the draft,
66 the draft being sent is encapsulated in the failure notice.
67 This permits easy \pgm{burst}'ing of the failure notice to retrieve the
70 if the posting was successful,
71 the draft is marked as having been sent.
73 \pitem{whatnow} prompting front-end for send.
74 A program which is called by \pgm{comp}, et. al.,
75 after the initial draft has been generated.
76 The \MH/ user can specify a different \pgm{whatnow} program,
77 which yields considerable extensibility.
79 \pitem{whom} report to whom a message would go.
80 A program which examines the addresses of the draft and expands
81 all user-defined aliases contained therein.
83 \pgm{whom} may actually interact with the message transport system
84 to determine the validity of the final addresses.
85 This program is also usually invoked by \pgm{comp}, et.~al.
88 \pitem{ali} list mail aliases.
89 A simple front-end to the \MH/ aliasing mechanism.
91 \pitem{ap} parse addresses 822--style.
92 A useful debugging tool for PostMasters who wish to examine how \MH/
93 interprets an Internet address.
95 \pitem{conflict} search for alias/password conflicts.
96 Another program used by system administrators to check the consistency of
97 \MH/ alias files, and portions of the local message transport agent.
99 \pitem{install-mh} initialize the MH environment.
100 A program which is automatically executed the first time a user issues an
102 This program performs once-only initialization of the user's \MH/ environment.
104 \pitem{mhmail} send or read mail.
105 A simple program generally used by other programs to generate messages.
106 The \pgm{mhmail} command is similar in purpose to the old \pgm{BellMail}
109 \pitem{post} deliver a message.
110 A complex \MH/ back-end that interacts with the local message transport agent
111 to enter messages through the posting slot.
112 (See the description of \pgm{send} above).
115 \pitem{inc} incorporate new mail.
116 A program that interacts with the local message transport agent
117 to retrieve messages from the user's maildrop.
119 \pitem{msgchk} check for waiting mail.
120 A program which reports the status of mail waiting in the user's maildrop.
122 \pitem{show} show (list) messages.
123 A program which lists messages to its standard output
124 (usually the user's terminal),
125 possibly invoking another program to do the actual listing.
126 Most users of \MH/ have \pgm{show} automatically call the \pgm{mhl} program
127 to format the message.
128 The \pgm{next} and \pgm{prev} programs are simply
129 \eg{show\ next} and \eg{show\ prev},
132 \pitem{mhl} produce formatted listings of MH messages.
133 A program which displays a message as directed by a template.
134 This permits the user to filter out uninteresting headers
135 and re-arrange other headers to a particular preference.
136 In addition to being invoked by \pgm{show},
137 the \pgm{mhl} program is optionally also
138 invoked by \pgm{forw} to format each message being forwarded;
139 invoked by \pgm{repl} to format the body of a message being replied-to,
140 if that message is being included in the reply draft;
142 invoked by \pgm{post} to format a message being sent as a blind-carbon-copy.
144 \pitem{rmm} remove messages.
145 A program that removes messages from an \MH/ folder,
146 optionally running a user-defined program instead of deleting them.
147 If no program is given,
148 the messages are ``softly'' removed,
149 so they may possibly be recovered later.
151 \pitem{scan} produce a one-line-per-message scan listing.
152 A program that generates a scan listing for messages.
153 Each line of the listing contains date, source, subject,
154 and possibly the initial body of the message.
156 \psect{Folder Handling}
157 \pitem{folder} set/list current folder/message.
158 A program used to list information concerning the current folder,
159 or set the current folder and/or message.
161 \pitem{folders} list all folders.
162 A program to list information on all folders
163 (actually, just a special case of the \pgm{folder} command).
164 Since the \MH/ folder structure may be recursive,
165 the user can indicate that \pgm{folders} should recursively examine all
168 \pitem{refile} file message(s) in (an)other folder(s).
169 A program to move (or copy) messages from a source folder to one or more
172 \pitem{rmf} remove folder.
173 A program that deletes a folder and all messages therein.
175 \psect{Message Selection}
176 \pitem{anno} annotate messages.
177 A program to arbitrarily annotate messages.
178 If the user so desires,
179 after distributing, forwarding, or replying-to a message,
180 \MH/ will automatically attach an annotation to the
181 original message indicating the date and addresses.
183 \pitem{mark} mark messages.
184 A program to manipulate user-defined sequences (lists of messages).
185 Usually, \pgm{mark} is not employed directly by the \MH/ user.
187 \pitem{pick} select messages by content.
188 A program to examine a list of messages and choose those which meet a
189 particular selection criterion.
190 The \pgm{pick} program is often used in \unix/ back-quoted operations to pass
191 message sequences to other \MH/ commands.
193 \pitem{sortm} sort messages.
194 A program to sort a list of messages according to the date given in a
197 \psect{Distribution List Handling}
198 \pitem{bbc} check on BBoards.
199 A front-end to run \pgm{msh} on a list of distribution lists which the
200 user isn't current on.
202 \pitem{bbl} manage a BBoard.
203 A (depreciated) program used to manually manage the local archives of a
205 These functions (archiving, expunging) are performed automatically by \MH/.
207 \pitem{burst} explode digests into messages.
208 A program used to decapsulate messages from ARPA Internet digests.
210 messages which have been encapsulated during forwarding
211 (i.e., with \pgm{forw\/})
212 can also be decapsulated using \pgm{burst}.%
213 \nfootnote{Similarly, blind-carbon-copies may be decapsulated,
214 though only socially mature users should do so.}
216 \pitem{msh} MH shell (and BBoard reader).
217 A monolithic program used to implement \MH/ commands on
218 messages arranged in a single file (maildrop format).
220 since distribution lists are kept in this format to minimize consumption of
223 \pitem{pack} compress a folder into a single file.
224 A program which takes messages stored in \MH/ format and places them in a
225 single file (using the same format known by \pgm{msh\/}).
227 \psect{Interface to the \unix/ File System}
228 \pitem{mhpath} print full pathnames of \MH/ messages and folders.
229 A program which maps \MH/-style names into the \unix/ file naming convention.
