mu-info - Man Page

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)

Nothing matching found; try a different query

database schema mismatch (11)

You need to re-initialize mu, see mu-init(1)

failed to acquire lock (19)

Some other program has exclusive access to the mu (Xapian) database
