MU INFO(1) General Commands Manual MU INFO(1)

mu info - show information about the mu database

mu [common options] info

mu info is the mu command for getting information about the mu database. Note that while running (e.g. mu4e), some of the information may be slightly delayed due to database caching.

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.

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.
