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 loca- tion; 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. 0. success 2. no matches found. Try a different query 11. database schema mismatch. You need to re-initialize mu, see mu- init(1) 19. failed to acquire lock.
