MU INFO(1) General Commands Manual MU INFO(1)

NAME

mu-info - show information

SYNOPSIS

mu [common options] info [<topic>]

DESCRIPTION

mu info is the mu command for getting information about various topics:

—
mu: general mu build information (default)
—
store: information about the message store
—
fields: table with all the query fields and flags
—
maildirs: list all maildirs under the store's root-maildir

Note that while running (e.g. mu4e), some of the store information can be delayed due to database caching.

COMMON OPTIONS

-d, --debug

makes mu generate extra debug information, useful for debugging the program itself. By default, debug information goes to the log file, ~/.cache/mu/mu.log. It can safely be deleted when mu is not running. When running with --debug option, the log file can grow rather quickly. See the note on logging below.

-q, --quiet

causes mu not to output informational messages and progress information to standard output, but only to the log file. Error messages will still be sent to standard error. Note that mu index is much faster with --quiet, so it is recommended you use this option when using mu from scripts etc.

--log-stderr

causes mu to not output log messages to standard error, in addition to sending them to the log file.

--nocolor

do not use ANSI colors. The environment variable NO_COLOR can be used as an alternative to --nocolor.

-V, --version

prints mu version and copyright information.

-h, --help

lists the various command line options.
