NAME

       muhelp - show help information about mu commands.

SYNOPSIS

       mu [common-options] help [<command>]

DESCRIPTION

       mu help provides help information about mu commands.

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 NOCOLOR 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
