NAME
mu info - show information about the mu database
SYNOPSIS
mu [common options] info
DESCRIPTION
mu info is the mu command for getting information about the mu database. Note that while running (e.g. mu4e), some of the information may be slightly 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.
EXIT CODE
This command returns 0 upon successful completion, or a non-zero exit code otherwise. Typical values are 2 (no matches found), 11 (database schema mismatch) and 12 (failed to acquire database lock).
no matches
found (2)
