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

mu-info - show information

mu [COMMON OPTIONS] info [TOPIC]

mu info is the mu command for getting information about various topics:

—
mu: general mu build information (default)
—
store: information about the message store
—
fields: table with all the query fields and flags
—
maildirs: list all maildirs under the store's root-maildir

Note that while running (e.g. mu4e), some of the store information can be delayed due to database caching.

Makes mu generate extra debug information, useful for debugging the program itself. Debug information goes to the standard logging location; see mu(1).

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.

Causes mu to not output log messages to standard error, in addition to sending them to the standard logging location.

Do not use ANSI colors. The environment variable NO_COLOR can be used as an alternative to --nocolor.

Prints mu version and copyright information.
