.SH NAME

mu cfind \- find contacts in the \fBmu\fR database and export them for use in
other programs.

.SH SYNOPSIS

.B mu cfind [options] [<pattern>]

.SH DESCRIPTION

\fBmu cfind\fR is the \fBmu\fR command for finding \fIcontacts\fR (name and
e-mail address of people who were either sender or receiver of mail). There
are different output formats available, for importing the contacts into
other programs.

.SH SEARCHING CONTACTS

When you index your messages (see \fBmu index\fR), \fBmu\fR creates a list of
unique e-mail addresses found and the accompanying name. In case the same
e-mail address is used with different names, the most recent non-empty name is
used.

\fBmu cfind\fR starts a search for contacts that match a \fIregular
expression\fR. For example:

.nf
   $ mu cfind '@gmail\.com'
.fi

would find all contacts with a gmail-address, while

.nf
   $ mu cfind Mary
.fi

would find all contact with Mary in either name or e-mail address.

If you do not specify any search expression, \fBmu cfind\fR will return the
full list of contacts.

The regular expressions are Perl-compatible (as per the PCRE-library).

.SH OPTIONS

.TP
\fB\-\-format\fR=\fIplain|mutt-alias|mutt-ab|wl|org-contact|bbdb|csv\fR
sets the output format to the given value. The following are available:

.nf
| --format=   | description                       |
|-------------+-----------------------------------|
| plain       | default, simple list              |
| mutt-alias  | mutt alias-format                 |
| mutt-ab     | mutt external address book format |
| wl          | wanderlust addressbook format     |
| org-contact | org-mode org-contact format       |
| bbdb        | BBDB format                       |
| csv         | comma-separated values            |
.fi

.TP
\fB\-\-personal\fR only show addresses seen in messages where one of 'my'
e-mail addresses was seen in one of the address fields; this is to exclude
addresses only seen in mailing-list messages. See the \fB\-\-my-address\fR
parameter in \fBmu index\fR.

.TP
\fB\-\-after=\fR\fI<timestamp>\fR only show addresses last seen after
\fI<timestamp>\fR. \fI<timestamp>\fR is a UNIX \fBtime_t\fR value, the number
of seconds since 1970-01-01 (in UTC).

From the command line, you can use the \fBdate\fR command to get this
value. For example, only consider addresses last seen after 2009-06-01, you
could specify
.nf
  --after=`date +%s --date='2009-06-01'`
.fi

.SH RETURN VALUE

\fBmu cfind\fR returns 0 upon successful completion -- that is, at least one
contact was found. Anything else leads to a non-zero return value, for
example:

.nf
| code | meaning                        |
|------+--------------------------------|
|    0 | ok                             |
|    1 | general error                  |
|    2 | no matches (for 'mu cfind')    |
.fi

.SH INTEGRATION WITH MUTT

You can use \fBmu cfind\fR as an external address book server for
\fBmutt\fR. For this to work, add the following to your \fImuttrc\fR:

.sh
set query_command = "mu cfind --format=mutt-ab '%s'"
.si

Now, in mutt, you can easily search for e-mail address using the
\fBquery\fR-command, which is (by default) accessible by pressing \fBQ\fR.

.SH ENCODING

\fBmu cfind\fR output is encoded according to the current locale except for
\fI--format=bbdb\fR. This is hard-coded to UTF-8, and as such specified in the
output-file, so emacs/bbdb can handle it correctly without guessing.
