mscan
generate one-line message summaries

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

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:
Only print message numbers (or filenames, if the message is not in the current sequence).
Force ISO date output, even for ‘%d’.
format
Format according to the string format, inspired by printf(3).
The following formatting codes may be used (wd overrides the default width):
Newline.
Tab.
A plain ‘%’.
[
wd
]b
Human-readable size of the message (in kilobytes).
A ‘>’ on the current message, otherwise a blank.
[
wd
]d

[
wd
]D

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

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.

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