MU HELP(1) General Commands Manual MU HELP(1)

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. 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.

EXIT CODE

This command returns 0 upon successful completion, or a non-zero exit code otherwise.
