* Mu Cheatsheet
|
|
|
|
Here are some tips for using =mu=. If you want to know more, please refer to the =mu= man pages. For a quick warm-up, there's also the =mu-easy= man-page.
|
|
|
|
** Indexing your mail
|
|
#+html:<pre> $ mu index</pre>
|
|
|
|
If =mu= did not guess the right Maildir, you can set it explicitly:
|
|
|
|
#+html:<pre> $ mu index --maildir=~/MyMaildir</pre>
|
|
|
|
*** Excluding directories from indexing
|
|
|
|
If you want to exclude certain directories from being indexed (for example,
|
|
directories with spam-messages), put a file called =.noindex= in the directory
|
|
to exlude, and it will be ignored when indexing (including its children)
|
|
|
|
** Finding messages
|
|
|
|
After you have indexed your messages, you can search them. Here are some
|
|
examples. Also note the =--threads= argument to get a threaded display of
|
|
the messages, and =--color= to get colors (both since 0.9.7).
|
|
|
|
*** messages about Helsinki (in message body, subject, sender, ...)
|
|
#+html:<pre> $ mu find Helsinki</pre>
|
|
|
|
*** messages to Jack with subject jellyfish containing the word tumbleweed
|
|
#+html:<pre> $ mu find to:Jack subject:jellyfish tumbleweed</pre>
|
|
|
|
*** messages between 2 kilobytes and a 2Mb, written in December 2009 with an attachment from Bill
|
|
#+html:<pre> $ mu find size:2k..2m date:20091201..20093112 flag:attach from:bill</pre>
|
|
|
|
*** signed messages about apples *OR* oranges
|
|
#+html:<pre> $ mu find flag:signed apples OR oranges</pre>
|
|
|
|
*** messages about yoghurt in the Sent Items folder (note the quoting):
|
|
#+html:<pre> $ mu find maildir:'/Sent Items' yoghurt</pre>
|
|
|
|
|
|
*** unread messages about things starting with 'soc' (soccer, society, socrates, ...)
|
|
#+html:<pre> $ mu find 'subject:soc*' flag:unread</pre>
|
|
|
|
Note, the '*' only works at the /end/ of a search term, and you need to
|
|
quote it or the shell will interpret it before =mu= sees it.
|
|
(searching using the '*' wildcard is available since mu 0.9.6)
|
|
|
|
*** finding messages with images as attachment
|
|
#+html:<pre> $ mu find 'mime:image/*' </pre>
|
|
(since mu version 0.9.8)
|
|
|
|
*** finding messages with 'milk' in one of its text parts (such as text-based attachments):
|
|
#+html:<pre> $ mu find embed:milk </pre>
|
|
(since mu version 0.9.8)
|
|
|
|
*** finding /all/ your messages
|
|
#+html:<pre> $ mu find ""</pre>
|
|
(since mu version 0.9.7)
|
|
|
|
** Finding contacts
|
|
|
|
Contacts (names + email addresses) are cached separately, and can be
|
|
searched with =mu cfind= (after your messages have been indexed):
|
|
|
|
*** all contacts with 'john' in either name or e-mail address
|
|
#+html:<pre> $ mu cfind john</pre> =mu cfind= takes a regular expression for matching.
|
|
|
|
You can export the contact information to a number of formats for use in
|
|
e-mail clients. For example:
|
|
|
|
*** export /all/ your contacts to the =mutt= addressbook format
|
|
#+html:<pre> $ mu cfind --format=mutt-alias</pre>
|
|
|
|
Other formats are: =plain=, =mutt-ab=, =wl= (Wanderlust), =org-contact=, =bbdb= and =csv= (comma-separated values).
|
|
|
|
** Retrieving attachments from messages
|
|
|
|
You can retrieve attachments from messages using =mu extract=, which takes a
|
|
message file as an argument. Without any other arguments, it displays the
|
|
MIME-parts of the message. You can then get specific attachments:
|
|
|
|
#+html:<pre> $ mu extract --parts=3,4 my-msg-file</pre>
|
|
|
|
will get you parts 3 and 4. You can also extract files based on their name:
|
|
|
|
#+html:<pre> $ mu extract my-msg-file '.*\.jpg'</pre>
|
|
|
|
The second argument is a case-insensitive regular expression, and the command
|
|
will extract any files matching the pattern -- in the example, all =.jpg=-files.
|
|
|
|
Do not confuse the '.*' /regular expression/ in =mu extract= (and =mu cfind=)
|
|
with the '*' /wildcard/ in =mu find=.
|
|
|
|
** Getting more colorful output
|
|
|
|
Some of the =mu= commands, such as =mu find=, =mu cfind= and =mu view=
|
|
support colorized output. By default this is turned off, but you can enable
|
|
it with =--color=, or setting the =MU_COLORS= environment variable to
|
|
non-empty.
|
|
|
|
#+html:<pre> $ mu find --color capibara</pre>
|
|
|
|
(since =mu= version 0.9.6)
|
|
|
|
** Integration with mail clients
|
|
|
|
The =mu-find= man page contains examples for =mutt= and =wanderlust=. And
|
|
since version 0.9.8, =mu= includes its own e-mail client for =emacs=, =mu4e=.
|
|
|
|
** Viewing specific messages
|
|
|
|
You can view message contents with =mu view=; it does not use the database
|
|
and simply takes a message file as it's argument:
|
|
|
|
#+html:<pre> $ mu view ~/Maildir/inbox/cur/message24</pre>
|
|
|
|
You can also use =--color= to get colorized output, and =--summary= to get a
|
|
summary of the message contents instead of the whole thing.
|
|
|
|
** Further processing of matched messages
|
|
|
|
If you need to process the results of your queries with some other program,
|
|
you can return the results as a list of absolute paths to the messages found:
|
|
|
|
For example, to get the number of lines in all your messages mentioning /banana/, you could use something like:
|
|
|
|
#+html:<pre> $ mu find --exec='wc -l'</pre>
|
|
|
|
Note that we use 'l', so the returned message paths will be quoted. This is
|
|
useful if you have maildirs with spaces in their names.
|
|
|
|
For further processing, also the ~--format=(xml|sexp)~ can be useful. For
|
|
example,
|
|
|
|
#+html:<pre> $ mu find --format=xml pancake</pre>
|
|
|
|
will give you a list of pancake-related messages in XML-format.
