NAME¶mu_cfind - find and export contacts in the mu database
SYNOPSIS¶mu cfind [options] [<pattern>]
DESCRIPTION¶mu cfind is the mu command for finding contacts (name and e-mail address of people who were either an e-mail's sender or receiver). There are different output formats available, for importing the contacts into other programs.
SEARCHING CONTACTS¶When you index your messages (see mu index), mu creates a list of unique e-mail addresses found and the accompanying name, and caches this list. In case the same e-mail address is used with different names, the most recent non-empty name is used.
mu cfind starts a search for contacts that match a regular expression. For example:
$ mu cfind '@gmail.com'
would find all contacts with a gmail-address, while
$ mu cfind Mary
lists all contacts with Mary in either name or e-mail address.
If you do not specify a search expression, mu cfind returns the full list of contacts. Note, mu cfind uses a cache with the e-mail information, which is populated during the indexing process.
The regular expressions are Perl-compatible (as per the PCRE-library used by GRegex).
- sets the output format to the given value. The following are available:
| --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 (*) |
(*) CSV is not fully standardized, but mu cfind follows some common practices: any double-quote is replaced by a double-double quote (thus, "hello" become ""hello"", and fields with commas are put in double-quotes. Normally, this should only apply to name fields.
- --personal 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 --my-address parameter in mu index.
- --after=<timestamp> only show addresses last seen after
- <timestamp>. <timestamp> is a UNIX time_t
value, the number of seconds since 1970-01-01 (in UTC).
From the command line, you can use the date command to get this value. For example, only consider addresses last seen after 2009-06-01, you could specify
--after=`date +%s --date='2009-06-01'`
RETURN VALUE¶mu cfind returns 0 upon successful completion -- that is, at least one contact was found. Anything else leads to a non-zero return value:
| code | meaning | |------+--------------------------------| | 0 | ok | | 1 | general error | | 2 | no matches (for 'mu cfind') |
INTEGRATION WITH MUTT¶You can use mu cfind as an external address book server for mutt. For this to work, add the following to your muttrc:
set query_command = "mu cfind --format=mutt-ab '%s'"
Now, in mutt, you can search for e-mail addresses using the query-command, which is (by default) accessible by pressing Q.
ENCODING¶mu cfind output is encoded according to the current locale except for --format=bbdb. This is hard-coded to UTF-8, and as such specified in the output-file, so emacs/bbdb can handle things correctly, without guessing.
