mpick — advanced message filter

mpick [-T] [-v] [-t test] [msglist ...]

mpick prints all matching messages.

If used interactively, mpick will default to the current sequence. Otherwise, mpick will read filenames from the standard input.

The options are as follows:

Include whole thread.
test
Only show messages matching the expression test, see TESTS.
Print how many messages were tested and picked to standard error.

mpick message lists (msglist) are mostly compatible with mailx(1). They are message specifications used as shortened TESTS, and can include:

n
Message number n.
n:m, n-m
An inclusive range of message numbers between n and m.
address
All messages from address.
string
All messages with string in the subject line (case ignored).
c
All messages of type c, where c shall be one of:
Draft messages.
Passed (resent, forwarded or bounced) messages.
Replied messages.
Flagged messages.
, T
Deleted messages.
New messages.
Old messages.
, S
Read messages.
Unread messages.

mpick tests are given by the following EBNF:

             | <expr> && <expr>  -- conjunction

<str>      ::= " ([^"] | "")+ "  -- use "" for a single " inside "
             | $[A-Za-z0-9_]+    -- environment variable

The mpick utility exits 0 on success, and >0 if an error occurs.

You can pick mails to move them into another maildir.

mv $(mlist ./INBOX | mpick -t 'from =~ "@github"') ./github/cur

Or you can use mpick to pick mails from the current sequence.

mpick -t 'subject =~~ "mblaze"' | mscan

A more advanced mpick expression to pick mails in a certain time span, which are flagged as replied or not seen.

mpick -t 'date >= "2016-01-01" && date < "2017-01-01" && (replied || !seen)'

And to find other mblaze users.

mpick -t '"User-Agent" =~~ "mblaze"' | mscan
