NAME
mu help - 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 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
