NAME

     mscan — generate one-line message summaries

SYNOPSIS

     mscan [-I] [-n] [-v] [-f format] msgs ...

DESCRIPTION

     mscan prints a one line summary for each message.  (See mmsg(7) for the message argument syntax.)

     If no msgs are specified, mscan reads filenames from the standard input, or scans the mails in the current
     sequence if used interactively.

     By default, mscan will spawn a pager on its output when used interactively.  See ENVIRONMENT for details on
     how to control this behaviour.

     The default format is

           %c%u%r %-3n %10d %17f %t %2i%s

     that is, for each message, mscan prints relevant flags, the sequence number (if applicable), the date, the
     originator, and the subject of the message (possibly indented).  A default mscan format may be specified in
     the user's mblaze-profile(5).

     The options are as follows:

     -I      Force ISO date output, even for ‘%d’.

     -n      Only print message numbers (or filenames, if the message is not in the current sequence).

     -v      Print how many messages were scanned to standard error.

     -f format
             Format according to the string format, inspired by printf(3).

             The following formatting codes may be used (wd overrides the default width):

             \n      Newline.

             \t      Tab.

             %%      A plain ‘%’.

             %[wd]b  Human-readable size of the message (in kilobytes).

             %c      A ‘>’ on the current message, otherwise a blank.

             %[wd]d  Adaptive date of the message.  When wd is greater or equal to 19, the timestamp is shown in
                     dottime format (https://dotti.me/).

             %[wd]D  ISO date of the message (year, month, day).  When wd is greater or equal to 16, the hour-
                     minute timestamp will also be shown.  When wd is greater or equal to 19, seconds will also
                     be shown.

             %[wd]f  The ‘From:’ (or ‘To:’, if the message is from us).

             %[wd]F  The maildir folder the message resides in.

             %[wd]i  wd (default: 1) spaces per indentation depth in the thread tree.

             %[wd]I  The ‘Message-ID:’ of the message.

             %M      The raw maildir flags of the message.

             %[wd]n  The number of the message in the current sequence.

             %r      A ‘-’ on a replied-to message, or a ‘:’ on a forwarded message, or a blank.

             %[wd]R  The filename of the message.

             %[wd]s  The subject of the message (defaults to remaining width).

             %[wd]S  The subject of the message (defaults to remaining width), with leading ‘Re:’, ‘Fwd:’ etc.
                     stripped.

             %t      A ‘>’ if you are in ‘To:’, a ‘+’ if you are in ‘Cc:’, a ‘:’ if you are in ‘Resent-To:’, or
                     a blank.

             %u      An ‘*’ on a flagged message, a ‘.’ on an unseen message, an ‘x’ on a trashed message, or a
                     blank.

MESSAGE FLAGS

     >   The current message
     .   An unseen message
     x   A trashed message
     *   A flagged message
     -   A replied-to message

SUBJECT FLAGS

     >   You are in ‘To:’
     +   You are in ‘Cc:’
     :   You are in ‘Resent-To:’

ENVIRONMENT

     MBLAZE_PAGER  Any non-empty value of the environment variable MBLAZE_PAGER is used instead of the standard
                   pagination program, specified in PAGER.  When empty, or set to ‘cat’, no pager is spawned.

EXIT STATUS

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