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
