64 searches within a folder for messages with the specified
65 contents, and then identifies those messages. Two types of search
66 primitives are available: pattern matching and date constraint
71 is used to perform the matching, so the
72 full regular expression (see
80 is used directly, and with the others, the grep pattern constructed is:
83 `component[ \\t]*:\&.*pattern'
86 This means that the pattern specified for a
89 everywhere in the message, including the header and the body, while
90 the other pattern matching requests are limited to the single specified
91 component. The expression
94 `\-\|\-component\ pattern'
97 is a shorthand for specifying
100 `\-search \*(lqcomponent[ \\t]*:\&.*pattern\*(rq\ '
103 It is used to pick a component which is not one of \*(lqTo:\*(rq,
104 \*(lqCc:\*(rq, \*(lqDate:\*(rq, \*(lqFrom:\*(rq, or \*(lqSubject:\*(rq.
106 .RB \*(lq "pick\0\-\|\-reply\-to\0pooh" \*(rq.
108 Pattern matching is performed on a per\-line basis. Within the header
109 of the message, each component is treated as one long line, but in the
110 body, each line is separate. Lower\-case letters in the search pattern
111 will match either lower or upper case in the message, while upper case
112 will match only upper case.
116 switch is a pattern matching operation (as
117 described above), to find messages sent on a certain date the pattern
118 string must match the text of the \*(lqDate:\*(rq field of the message.
120 Independent of any pattern matching operations requested, the switches
126 may also be used to introduce date/time
127 constraints on all of the messages. By default, the \*(lqDate:\*(rq
128 field is consulted, but if another date yielding field (such as
129 \*(lqBB\-Posted:\*(rq or \*(lqDelivery\-Date:\*(rq) should be used, the
139 will actually parse the date
140 fields in each of the messages specified in `msgs' and compare them
141 to the date/time specified. If
143 is given, then only those
144 messages whose \*(lqDate:\*(rq field value is chronologically after the
145 date specified will be considered. The
148 complimentary action.
154 switches take legal 822\-style date
155 specifications as arguments.
157 will default certain missing
158 fields so that the entire date need not be specified. These fields
159 are (in order of defaulting): timezone, time and timezone, date, date
160 and timezone. All defaults are taken from the current date, time,
163 In addition to 822\-style dates,
165 will also recognize any of
166 the days of the week (\*(lqsunday\*(rq, \*(lqmonday\*(rq, and so on),
167 and the special dates \*(lqtoday\*(rq, \*(lqyesterday\*(rq (24 hours
168 ago), and \*(lqtomorrow\*(rq (24 hours from now). All days of the
169 week are judged to refer to a day in the past (e.g., telling \fIpick\fR
170 \*(lqsaturday\*(rq on a \*(lqtuesday\*(rq means \*(lqlast\ saturday\*(rq
171 not \*(lqthis\ saturday\*(rq).
173 Finally, in addition to these special specifications,
176 also honor a specification of the form \*(lq\-dd\*(rq, which means
177 \*(lqdd days ago\*(rq.
180 supports complex boolean operations on the searching primitives
194 pick\0\-after\0yesterday\0\-and
195 \-lbrace\0\-from\0freida\0\-or\0\-from\0fear\0\-rbrace
199 identifies messages recently sent by \*(lqfrieda\*(rq or \*(lqfear\*(rq.
201 The matching primitives take precedence over the
203 switch, which in turn takes precedence over
205 which in turn takes precedence
208 To override the default precedence, the
212 switches are provided, which act just like opening and closing
213 parentheses in logical expressions.
215 If no search criteria are given, all the messages specified on the
216 command line are selected (this defaults to \*(lqall\*(rq).
218 Once the search has been performed, if the
221 message numbers of the selected messages are written to the standard
222 output separated by newlines. This is
225 quickly generating arguments for other
227 programs by using the
228 \*(lqbackquoting\*(rq syntax of the shell. For example, the command
231 scan\0`pick\0+todo\0\-after\0\*(lq31 Mar 83 0123 PST\*(rq`
236 those messages in the indicated folder which meet the
237 appropriate criterion. Note that since
240 are written out prior to
242 invocation, you need not give
243 the folder argument to
250 switch may be given once for each sequence the user wishes to define.
251 For each sequence named, that sequence will be defined to mean exactly
252 those messages selected by
257 pick\0\-from\0frated\0\-seq\0fred
260 defines a new message sequence for the current folder called
261 \*(lqfred\*(rq which contains exactly those messages that were selected.
265 will zero the sequence before adding it. This
266 action can be disabled with the
268 switch, which means that the
271 will be added to the sequence, if it
272 already exists, and any messages already a part of that sequence will

318 In previous versions of
327 the selected messages. This was rather
328 \*(lqinverted logic\*(rq from the UNIX point of view, so
330 was changed to define sequences and output those sequences. Hence,
332 can be used to generate the arguments for all other
334 commands, instead of giving
336 endless switches for invoking those commands
339 Also, previous versions of
341 balked if you didn't specify
342 a search string or a date/time constraint. The current version does
343 not, and merely matches the messages you specify. This lets you type
347 show\0`pick\0last:20\0\-seq\0fear`
354 mark\0\-add\0\-nozero\0\-seq\0fear\0last:20

375 switch it applies to.
379 is used in a back\-quoted operation, such as
382 scan\0`pick\0\-from\0jones`
387 selects no messages (e.g., no messages are from
388 \*(lqjones\*(rq), then the shell will still run the outer command (e.g.,
390 Since no messages were matched,
393 no output, and the argument given to the outer command as a result of
396 is empty. In the case of
399 the outer command now acts as if the default `msg' or `msgs' should be
400 used (e.g., \*(lqall\*(rq in the case of
403 unexpected behavior, if
405 was given, and if its standard output is not a tty, then
407 outputs the illegal message number \*(lq0\*(rq
408 when it fails. This lets the outer command fail gracefully as well.
410 The pattern syntax \*(lq[l-r]\*(rq is not supported; each letter to be
411 matched must be included within the square brackets.
