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. 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.
