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.  Debug  information
       goes to the standard logging location; see mu(1).

   -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  standard
       logging location.

   --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.
