.Sh DESCRIPTION
.Nm
prints the messages
.Ar msgs
where the value of
.Ar header
matches the POSIX Extended Regular Expression
.Ar regex .
.Pp
If
.Ar header
is empty,
.Nm
will instead match against the Maildir flags of the messages.
.Pp
If
.Ar header
is
.Sq Li "/" ,
.Nm
will instead search the plain text parts of the
.Em body
of the messages.
.Pp
See
.Xr mmsg 7
for the message argument syntax.
If no
.Ar msgs
are passed, and
.Nm
is used interactively,
.Nm
will default to the current sequence.
.Pp
The options are as follows:
.Bl -tag -width Ds
.It Fl a
Search for
.Ar regex
only in all RFC 2822 address parts in
.Ar header .
.It Fl c
Don't print matching messages,
just display the number of matched messages.
.It Fl d
Decode the
.Ar header
according to RFC 2047 first.
.It Fl i
Match
.Ar regex
case insensitively.
.It Fl m Ar max
Do not show more than
.Ar max
matches.
.It Fl q
Quiet mode: do not print anything,
quit as soon as possible.
.It Fl v
Invert the match, print (or count) all messages where
.Ar regex
does not match.
.Sh EXIT STATUS
.Nm
returns with exit status 0 if a match was found,
with exit status 1 if no match was found,
and with exit status higher than 1 if an error occurred.
