-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.
