--muhome¶

Use a non-default directory to store and read the database, write the logs, etc. By default, mu uses the XDG Base Directory Specification (e.g. on GNU/Linux this defaults to ~/.cache/mu and ~/.config/mu). Earlier versions of mu defaulted to ~/.mu, which now requires --muhome=~/.mu.

The environment variable MUHOME can be used as an alternative to --muhome. The latter has precedence.

-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.
